Are the pros shooting really well in the memorial or did the ratings calculation get changed? it seems like the hot round is normally around 1060 for a tourney of the best people, but in the memorial they are shooting 1080 and 1090 for the high rounds.

The online formula is producing numbers roughly 5 points higher than they will probably end up when done officially. But the top scores are really that good. The bigger the field size, the more likely you'll see exceptional rounds.
chris
Mar 05 2006, 01:57 PM
I was thinking the same thing, usually you do only see 1 or 2 round above 1050-60 at the larger events, if someone gets hot maybe a 1070 or even 1080. But there's 16 rounds over 1050 including 3 masters and a 1090+?, those all seem a little high ( average of 8 1050+ ratings per round) . . . 48 people shot over 1000 the 2nd round just in the open division and only 26 are rated over 1000.

is the whole field skewed on the high side or are there just more great scores? if the former, could it be layout by division data entry error?
ck34
Mar 05 2006, 04:14 PM
The 8-pt upshift from 2005 is still in the online formula meaning the average of all round ratings will be 8 points higher than the average of all propagator ratings. That boost factor is phasing out this year now that all active players got the boost in 2005. There doesn't appear to be a mistake in the course layout assignments by division.

yes, but is it up or down? and so is a stagnant rating. depends on how many new better members are joining.
ck34
Mar 05 2006, 07:52 PM
An increase in rating means you're getting better among all disc golfers. A change in ranking up or down has an unknown skill component because the primary effect is produced by the number of members expiring, joining or renewing. Your ranking can get worse when you are getting better and your ranking can get better when you're playing worse. Rankings among member subsets would work better if the PDGA went to yearround renewals so that the number of members at any point in time was increasing (hopefully) at a steady rate and not have the big swings from December thru about May under the current process.

i believe a helpful person recently solved that equation, but he was forced to undo what he did and his hands were subsequently tied... still if you wish you can go to the ratings page and then perform a time-consuming manual count based on the last ratings update... it will take a while though because you'll have to count amongst 1266 Pro Men, 107 Pro Women, a bunch of Am. Men and Many Am. Women to see where you fall.

A higher rating IS better relative to the member pool and to the total pool of disc golfers because a player earning rating points means others are losing them. That's how it works. Not true about rankings.

Good. I still find rankings based on where one's rating places one amongst all PDGA members to be a meaningful number that interests me and motivates me as a PDGA member. I also find it meanigful to see where the rating of a great female PDGA player like Des, Juliana or Nicole Frazer (Am.) ranks them against men. I find it a testimony to how skilled these women are and not some kind of slight against men like me who they have outperformed.

It's not real. It's an illusion you had nothing to do with. Random actions of people renewing at a certain time. Progress of the calendar from grace period to not any more.

Maybe there are more disc golfers. Some good ones now joining the PDGA and getting rated. This could be a sign of growth or just baggers finally paying up. I know I have passed people since I signed up and have had much better disc golfers sign up after me.

Well, given that my moribund rounds are suddenly being rated 950-970, I don't think anyone is going to need an Am 2 or Am 3 division by the end of the year. I have not gotten any better from two years ago. I can tell that just by my scores at courses that have not changed much. But suddenly I'm getting credit for all these rounds that are 30 and 40 points over my rating. That will make all the intermediates who aren't getting any better advanced players by the year's end.

My 1024 rated round (brag off) was skewed by wind in the afternoon for the other divisions. (brag on) I think it was still 1000+ worthy, but prolly more like 1005-ish than in the 1020s.
FWIW, I think a 55 on the Vista layout should be the highest rated round ever. That was just sick.

I agree with Rhett on the idea that wind helped him by adversely affecting the other players. With tee times being spead out from 8 in the morning till as late as 1:30 in the afternoon there is a lot of room for weather changes. I played my last round in some pretty heavy wind and spoke with players who played in my division two hours earlier saying that there was absolutely no wind at all. That's going to affect some serious differentiation in round scores, especially since most of the lower rated players played with no wind, and the highest rated players had very heavy wind for most of the round.
Take Celmer and I for example, we were two of the three players rated over 960, and our final round we each shot 930 rated rounds. If everyone had had to play in the conditions we had, our 6 over par rounds probably would have been rated in the 960s. And the opposite happened for our first round at Fountain, we both tee'd off early before the wind and ended up shooting 1005 rounds while the other players had more wind. But I'm sure that our 1 under par rounds would have been rated only 980ish if everyone had been playing at the same time.
I think anytime you have different tee times instead of shotguns starts, on a course with varied weather conditions, you are going to see the ratings do some pretty crazy things, SUPER high ratings, and then potentially SUPER low ratings.

It's kinda funny how that works out sometimes, but it's simple math. At a course with a higher SSA, each stroke is worth less rating points, and for a course with lower SSA, vice versa.
You beat him first round by 11, and got a rating 66 points higher. Each stroke was worth 6 rating points.
He beat you 2nd round by 3, and got a rating 27 points higher. Each stroke was worth 9 rating points.
The final round he beat you by 6 and got a rating 42 points higher, each stroke worth 7 rating points.
His total rating points above you on the final 2 courses, 42+27=69, while your rating points above him on the first course, 62, therefore his rating average for the tourney is better. Basically, by Tanner shooting better than Dave on the courses with lower SSA, he actually earned a better ratings average but shot 2 strokes worse for the tournament. Aren't ratings fun! :D
ck34
Mar 08 2006, 10:48 PM
We've haven't decided a formal policy on courses played with tee times. However, we have discussed breaking up the ratings calculations into half day or 1/3 days and doing calculations for each separate group like there were 2 or 3 separate rounds in a day on that layout.

I had discussed the adjustment factor that boosts the SSA by one shot for the 875 average group of propagators versus the 975 average group of propagators. You can now see where sometimes the Am group playing the same course will get better ratings than the Pro group playing the same course.

I agree that Tee Times are hard to work with, it almost comes down to luck of the draw for the first day as in the case of the AM's at Fountains. Anyone teeing off after 11:00 am saw'll strong winds, but if they played well and then played well for the second round at Vista they got to play in the wind for round 3 on the last day. Doesn't seem fair if you are playing for strong ratings but then again if you play well in adverse conditions during your rounds, then you are a sleeper coming into a tournament

We'll just have to see when the scores are posted but I think it's going to be just another one of Barry's routine 1080+ rounds. When you're at 1035, you have to have a few rounds above 1070 to offset those "bad rounds" of a 1000 or less (like Saturday at Tower).

-15 is out of this world even on an easier course. I played with Johnny Lissaman when he threw a -15 on Rum Village at the 1996 Worlds, which was unbelievable to watch. Of course his brother Geoff then shot a -17 a day or so later to set the Worlds record for lowest round.

Jul 18 2006, 10:08 AM
For players in the 1030+ rating range, it's not uncommon for them to regularly shoot rounds over 1050 and there were a few at BHMO. I looked at the average rating of the Pros and the average round ratings and they are both about the same which is the way it should be. Currently, the remaining small boost factor left over from late 2005 is still in the online formula which is boosting the ratings 2-3 points. This won't be in the official calcs in the Sept update. For BHMO, the average rating of the props is about 970 and the average round rating ranges from 972-974 for the three rounds so the numbers are normal for such a highly rated field of players.

*Standing Ovation*
It all goes back to my basic question which no one, including Chuck, has ever been able to answer with anything logically other than "thats no possible"
Let's say you have a NT at a course with a SSA of 49 ( I choose that b/c when SSA is around there, it works out to almost exactly 10 points a throw)
The weather is great. For no reason at all other than coincednce, the hot round is 49, which means SSA would probably be around 53 for the round (roughly). Everyone who shot 52 or better was 1000 or better.
The next round, same conditions, same course. There are 17 scores better than 49, including 8 by players rated less than 1000.
Even though everything was the same, a 49 the first round would be rated much much higher than the second round. That to me is a problem. The way to get a really high rated round is to play good when no one else does!!
We need to get basing the formula more on the course played rather than the players playing it. Top pros get amazing round ratings and ams get screwed.

If you think this thru it makes no sense. What you're saying is that a particular course should produce an average round rating of say 950 regardless of whether a pool of 850 players or 1000 rated players play an event there. If that were the case, no one with a rating greater than the fixed course value would ever play that course and Ams would flock to play those courses to pick up rating points.
The way the ratings work and the only way that makes sense is for the ratings earned by propagators in each round on average is exactly the average of the ratings of these propagators. A player can earn higher ratings based strictly on how they play. It makes little difference whether you play in a high average rated pool of players or low average rated pool of players. The small factor for lower pool rating averages introduced last year now makes the pool rating average for the event neutral in terms of ratings. At one time, playing in higher rated events might have produced ratings 5-10 points better than a lower rated pool but that effect has been removed since 2005.
sandalman
Jul 19 2006, 09:29 AM
the formula is fine, and no one can seriously argue that the ratings are "wrong". they do what they are intended to do - provide a relative measure of disc golf skill - extremely well.
that being said, there it may not be possible to completely eliminate one of the effects people complain about - the the same round score with different gators will yield a different rating. and that does not feel right, even though the anomoly has been reduced significantly from when ratings started.
bottom line: you can completely please everyone.

My buddy shoots a 54 (hes an am playing at the course with just ams) it was rated 999.
There still is a problem!
ck34
Jul 19 2006, 10:02 AM
"Variance" means the numbers will vary. It used to be that a pro pool might get ratings ranging from -20 to +40 points better than an Am pool rated 100 points lower. Now it ranges from -30 to +30 with most values between -10 to +10. That's one throw in 50 or 2% variance. That's like the difference between 98 cents and $1.02. It's still basically a $1.
ryangwillim
Jul 19 2006, 11:49 AM
Disc Golf tournaments are competitions against other players. You are not playing against the course, you are playing against people.
I think the ratings are very accurate and provide what they are intended to provide. Your rating for a round shows how you performed in relation to everyone else you were competing with during that round. That is what we want to know, that it what it does.
Score doesn't really mean anything. If I shoot 10 under and Shultz shoots 13 under his performance was better. And that would be reflected by a roughly 30 point difference in rating. It wouldn't matter if this happened on a course with an SSA of 49 or 57. The system is very accurate and performs the intended function, which is stacking players according to skill level (when the are playing at the same time on the same course).
When you have players playing at different times and such even on the same course there are innumerable variables that can come into play that a course established SSA would be ludicrous.

I totally disagree with what you said about the players and the course.
If you shoot the highest rated round in history and shoot the course record by 8 strokes, what control do you have if someone two cards ahead of you just beat the recod by 9?
All you can do is be satisfied with your play.
As far as the ratings go....I think there needs to be more consistency within a course. There's no possible way a course can play easier than it is (it can play harder though). Who cares if 10 people kill it, why should they be penalized ratings wise for a good round. Who cares if everyone sucks, why should they be rewarded with a high rating for a bad round?

Conditions are never the same from round to round even if it seems like they are. It's like chaos theory when a butterfly batting its wings in Taiwan may produce a hurricane in the Atlantic. Every little thing may count much more than it appears.
The sun lights holes differently as the day progresses and cloud cover may continually shift making the perspective change. The leaves positions change. Items on the ground are in different positions. The wildlife is more or less active (birds chirping). The dew is gone. Players already have played a round and where they are personally in terms of attitude and energy is different. Players will be in different groups. The second round may be the last round (or not) in the event. A player already has a mental record of what they did on each hole in the first round that impacts what they do on their second round. Temperature is likely different. And we all know what losing a disc and the dynamics of cumulative tree whacks might do to the discs and some players' games.
We think of wind and rain as being the big difference factors in why one round has different scoring/ratings than another. I would contend that the subtleties of the other "smaller" factors are cumulatively just as important and we should be surprised when the SSA values come out as close as they usually do when humans are involved in producing the numbers.

It's the difference between course ratings and player ratings. We are talking about player ratings. The course means absolutely nothing in regards to player ratings. The only thing that matters is how you score in relation to the other players on said course. It seems that you are adding emotion into this, MTL. The course record means nothing in regards to a round rating. Neither does the difficulty of the course, or any other institution of thinking outside of mathematics. With round ratings, good and bad rounds are determined ONLY by your score in relation to other scores of that round, not what you think or feel was good.
If you shoot 2 under on a 'difficult' course and that is rated 989, then you turn around and shoot +5 on the same course the next round, but everyone else sucks much, much worse and u have the hot round and it is rated 1030, that is valid. You emotionally believe that you had a horrible round, but mathmatically you had a wonderful round IN RELATION to the other competitors. This tracking of numbers is what the 'player rating' is all about. Take all emotion out of the equation.
I hope this is making sense to someone.

Wow. Just wow.
A course with a low SSA has a larger number in the amount of points that represents a stroke. A course with a high SSA has a low number.
Therefore - It's really easy to shoot a high rated round when a course is around 48ish (b/c there is a larger amount of points invovled and an SSA of 48 usually means the course has many birdie opportunites). It's also really tough to shoot a high rated round on a very tough course (See Winthrop Gold and Renny Gold.)
KEnny shot that amazing 56 a few years ago at USDGC and it was 1078. Theres no way that a 56 on that course is comparable to a 42 on a course with an SSA of 48. A 56 is much much better. Ratings comapred these two rounds.
The course matters a lot.

chuck, you know i love the ratings, but this statement destroys credibility on this particular issue.
as i noted before, the people who start on Hole X in an afternoon round experience conditions closer to what players who finished on Hole X in the first round experienced than what their own pool-mates who finish on Hole X will experience.
using differing conditions as a reason for seperating round results is ignoring this truth.

On this I agree with you. I think that hot rounds on high SSA courses that are longer and with a higher par do not get accurate ratings (sometimes vastly lower than they should be) when compared to scores on low SSA courses that may be mostly pitch-n-putt.
I'll never understand why you still get hungup on the difference between a 999-rated round and 1009-rated round, however. That's silly.

using propogators from the same pool to establish the rating is going to be a whole lot more accurate than using any other measure. you cant use the course SSA, cuz that changes dramtically with the weather, foliage, etc. like chuck says, using gators to seed the system does introduce a slight variability - but only a tiny bit. certainly not enough to throw the integrity of the ratings system into question.

That may be true for an individual hole but the ratings are based on complete rounds. If you take a snapshot of the sun's angle, temperature, dew level, and scatter of debris on the ground, that will be different five hours apart and on average for each round. The course conditions are still only part of the differences in scenarios where the course is presumed to be the same in morning and afternoon. The people factors are more different between rounds including one not mentioned above which is the flow on the course in terms of hole delays either due to missing or hitting a usual stack up on certain holes or delays for a lost disc in your group or the one in front.
I already pointed out the number one reason for differences in SSA on the same course in "similar" conditions between Ams and Pros and that's the fact that there are more Am propagators who are under-rated than Pros of all ages. That produces lower SSA values. We know it and have an adjustment factor in the formula now to account for it so that there's a 50/50 chance now that you'll get a slightly better rating in an Am pool versus a Pro pool.

Stats from courses with low SSAs shouldn't be compared with those with high SSAs. Doing course and player ratings stats are much more complicated than most sports because the game field varies so widely. In basketball, you don't compare or combine player stats from courts that have 3-point lines at different distances or games with different time lengths.
In the same way, we should try not to compare course records from low SSA and high SSA courses. As we start to compile more records, we'll probably track course records in three or four SSA ranges along the lines of either: under 50, 50-60 and over 60, or under 46, 46-54, 54-63 and over 63.

My laser range finder is accurate within a yard in the range of 4-600 yards.
But 3 feet off, I'll still drop that deer.
Now it ranges from -30 to +30 with most values between -10 to +10. That's one throw in 50 or 2% variance
~1 stroke/round???
I'll still drop that deer. :D
It all goes back to my basic question which no one, including Chuck, has ever been able to answer with anything logically other than "thats no possible"
MTL, you've acknowledged the fact that there is variances in course difficulties and player pools. How reasonable is it to expect an accuracy of 0.49999... pts (enough that rounding doesn't affect accuracy)?
Inherient inaccuracies in number systems.
Variances in course difficulty and player pools.
Ergo...
It's NOT POSSIBLE.

My biggest issue concerning the ratings system.
If we are going to determine what players can and cannot play based on ratings, they have to be as accurate as possible (Which I still don't think it is). I'm not saying that there should be some chart saying if I shoot 49 on a course with a WCP of 50.2, it should be a 988 every time. I just feel that if I shoot a 49 with 15 1000+ rated players and its rated 988, then it should be rated 988 regardless of I'm the highest rated player or not.
Yeah ten points may not be a big deal. Add that together 10 times and then we get a big deal. This could be the difference in a pro having to play pro or and amatuer having to play advanced.
They aren't consistent and in no way speak of how you are currently playing (although I do like the way later rounds are double weighted and I do like that we aren't dropping 10% of the rounds anymore).
I think we need to go back to a system where ratings are just a novelty rather than a judegment.

Yea, let's go back to the system where the decision to play Recreational, Intermediate, or Advanced was based on your tournament experience, whether people felt you were sandbagging, what area of the country you lived in, or your arbitrary mood that day. Yea, let's just totally throw a out a reasonably accurate way to actually MEASURE and QUANTIFY a golfer's ability and characterize them as less 875, between 875 and 915, or greater than 915.

I get the feeling you don't quite get it. I assume you don't like batting averages, bowling averages, golf handicaps etc.
What do you propose we do then?
People new to the sport are usually getting better, so nothing can really account for that. I've been playing for 12 years and I'm still getting better and I believe my rating hasn't quite caught up with me yet. So how could any calculations account for that?
MTL21676
Jul 21 2006, 12:26 PM
I've probably forgotten more about disc golf than most people know.
I understand ratings and how they are calculated and see no consistency in them whatsoever.
People are shooting 1050 rounds all over the place now. I went back and research and found that the 2003 Seneca Creek NT (http://www.pdga.com/tournament/tournament_results.php?TournID=3425&year=2006&include_ratings=1#Open) had Ron Russell shoot the hot round by 4 strokes the third round. Look at the field. That would have been rated probably 1080 today.
Also, check out Cedar Hills (http://www.pdga.com/tournament/course_ratings_by_course.php?RatingCourseID=102) in Raleigh NC. The WCP on the same layout *note not the short tees or the gold layout* is from 46 .9 - 50.9. I live five minutes from the course and I can garuntee it doesn't randomly get 4 strokes harder or easier.
In fact, most courses have crazy rating differences.
Your refrences to batting averages and handicaps have no revelance. Those are taken from basic statistical laws regarding Number of successfull tries divided by number of attemps for baseball and average number of strokes over par for golf.
Until there is consistency in course desgin a handicap system does not work. I can tell you I shot a 54 at Zebulon park in North Carolina and unless you have played that course you have no clue if that is the best round I've ever shot or the worst round. I could go down the street to a ball golf course, shoot a 72 and you could know thats a good round without ever seeing the course.
Until we get a "Standarized" par (Which I understand WCP attempts to be), ratings are useless, inaccurate, and inconsistent.
MTL21676
Jul 21 2006, 12:28 PM
also, ratings are start to take over player's mental games. I've heard many players say they don't want to play certain courses because the ratings for that course are traditionally bad and know of people who quit during bad rounds b/c they don't want that round to get rated and screw there rating up.
What happened to going to a tournament to play a good course or learning from your bad rounds?

I agree with this. I hope that I'm still around when disc golf courses have to meet certain standards and qualifications to solve this problem.
The reality is, right now, we can't change all the courses, but we need a skill based system to keep everybody in check, plus it's cool.
As for your problem with tournaments coming up with different ratings, I have no idea. The ratings have been tweaked numerous times and maybe there's an inconsistency with the course info that was entered, I don't know. From what I've seen around here, the course ratings come out really close to each other in different tournaments with the same layout, even different years they are close.
MTL21676
Jul 21 2006, 12:54 PM
There are some courses where the ratings come out close to each other consistently.
It is the courses with WCP's around 47 - 54 that have the problem. These courses usually have 15 - 18 duece opportunites but many of these are tough holes where a three is not a bad score even though it is a par. and you may duece it 1 out of 10. Also, these are course where there are many 400 - 500 foot holes that not many people at all will 4 without a majot screw up and there will not be many twos (i.e the hole average is l;ike 3.1). Therefore the chance of variance in scores increases dramatically b/c both of these instances have a chance where a player could be on a shoot a 44 or a 45 and the next round shoot a 52 and not play too much worse.

ratings fight against standerized courses if anything b/c it compares them all. If there was a PDGA stipulation saying your course will not recieve ratings unless it falls between a SSA of X and Y, then they would. Now as long as there are enough propergators, we rate it. We are allowing who plays to determine the rating rather than the course to determine it itself.

I love the rating system and I think it's very accurate. I almost always know what my round was rated to within 5 points, therefore it must be pretty darn accurate. When I feel I shot a 1020 rated round it is always rated between 1015-1025! The only thing that is wrong with the system is that we give MTL a rating. If we didn't give him a rating then there would be no bitchn about anything and everyone would be happy! :p

Jul 23 2006, 03:23 PM
It seems like players who play courses with lower ssa's generally have higher ratings.
Without a doubt it is much easier to increase your rating if you are playing against players that have a higher rating than you, especially if a few of them shoot poorly!
I havent given Chuck a hard time about the ratings lately and agree its fairly accurate, but I still feel it should be done by averaging all the players ratings before the event and then averaging their scores and have nothing to do with amything else. The average score would be the average rating and then each stroke could be worth 6-10 points acording to the average score, with higher averages being worth 10 and the lower averages worth 6
Right now each stroke is worth more value from a round with a lower average. I feel it should be the other way around. Usually more players scores are bunched closer as the average round score goes up away from 54 which means its harder to put on seperation, which is why the value should be greater with the higher scores!
Of course I think all courses used for major compatition should be played on par 68-72 style courses to assure the winners have a well rounded game and not just the best putters are winning like in the past!
I have assumed a lot based on small samplings without much homework.
Can someone prove any of these theories or statements wrong?

No courses seem to have any wider variance than any others from event to event or year to year. You look at courses like Knob Hill and it's surprising how close the numbers have been for the same layout from year to year. The Castle Hayne course is the only one that appears to have hole designs that make it difficult to score as much below the SSA as some other courses in that SSA range. It's not a flaw in the calculation process, just something we discovered along the way. There are courses at the other end of the scale where it's easier than average to score low. It's not like there's a guarantee that every course is going to respond the same way in terms of ratings.
In ball golf, the courses used for handicapping are way more alike than what we use for ratings in DG. Ball golf courss have course ratings in pretty narrow range from maybe 67-74. Our ratings system has to cope with SSA values from 41-72.
ck34
Jul 24 2006, 11:11 AM
Right now each stroke is worth more value from a round with a lower average. I feel it should be the other way around.
It's not a choice we made, it's mathematical reality. Let's try an example where we have a Robot X that throws scores at 1000 rating and Robot Y that throws at 950. On a course with an SSA of 50, Robot X shoots 50 and Robot Y throws 55. If they played this course another time they would shoot the same scores of 50 and 55. Their total throws so far for 36 holes would be 100 and 110 respectively.
Now, let's say there's an unbelievably tough course that has an SSA of 100, exactly the same as playing two rounds twice on the SSA 50 course. Robot X would shoot 100 rated at 1000 and Robot Y would shoot 110 rated at 950. Note that their scores are 10 throws apart and 50 rating points different. That means that each throw is worth 5 points on a 100 SSA course rather than 10 points on the 50 SSA course.
If we now have the robots play a course like Winthrop with an SSA about 70, Robot X will shoot 70 and Robot Y will shoot 77. Remember that each robot shoots exactly their rating of 1000 and 950. So, on this course, the 7 throws difference in the score between them is worth 50 rating points. 50 divided by 7 works out to about 7 points per throw.
There's nothing magic about our ratings system that awards fewer points per throw as the SSA gets higher. That's just the way it works.

*Warning ratings compliment*
I personally like the fact that it is not 10 points a round for every course. I look at it like this. If you lose to someone on a course with an SSA of 45 by 6, he beat you on 13% of the course and you tied on the other 87%. If someone beats you on a course with an SSA of 60 by 6, he only beat you on 10% of the course.
The lower the SSA of a course the tougher it is to make up strokes and I think the ratings reflect that well. However, I would like to see some higher ratings for hot rounds on courses with SSA's over 65

There's nothing magic about our ratings system that awards fewer points per throw as the SSA gets higher. That's just the way it works.
I was following you up to this example. What you're saying is that the rating for a player will be the same for these 2 situations: 1) someone throws 40 on a course whose SSA is 50, and 2) someone throws 80 on a course whose SSA is 100.
Shouldn't the latter score be a much more impressive feat, to throw that well for twice as long?
If it is more impressive, is that taken into account by weighting the round of 80 on a 100-SSA course when calculating average ratings?
For example, when averaging the ratings over several rounds, if these were the ratings:
1010 on a course of SSA 50, weight factor = 1.0
1080 on a course of SSA 100, weight factor = 2.0
average rating = 1010 * 1.0 + 1080 * 2.0 / (1.0 + 2.0)
average rating = 1056.7
Is this what is done now (or something similar)?
Edited to add: even that wouldn't weight the latter round any more if the earlier round was rated 1080 on a 50-SSA course. Then the average would just work out to be 1080, as if both rounds were of equal accomplishment. But being consistently good over a longer period of time is known to be more difficult, so it seems this should be taken into account in ratings. Is it?

Bragging rights aside, isn't it generally better to have a lower rating than a higher one? Is there a bonus for a high rating I don't know about?

Right now each stroke is worth more value from a round with a lower average. I feel it should be the other way around.
It's not a choice we made, it's mathematical reality. Let's try an example where we have a Robot X that throws scores at 1000 rating and Robot Y that throws at 950. On a course with an SSA of 50, Robot X shoots 50 and Robot Y throws 55. If they played this course another time they would shoot the same scores of 50 and 55. Their total throws so far for 36 holes would be 100 and 110 respectively.
Now, let's say there's an unbelievably tough course that has an SSA of 100, exactly the same as playing two rounds twice on the SSA 50 course. Robot X would shoot 100 rated at 1000 and Robot Y would shoot 110 rated at 950. Note that their scores are 10 throws apart and 50 rating points different. That means that each throw is worth 5 points on a 100 SSA course rather than 10 points on the 50 SSA course.
If we now have the robots play a course like Winthrop with an SSA about 70, Robot X will shoot 70 and Robot Y will shoot 77. Remember that each robot shoots exactly their rating of 1000 and 950. So, on this course, the 7 throws difference in the score between them is worth 50 rating points. 50 divided by 7 works out to about 7 points per throw.
There's nothing magic about our ratings system that awards fewer points per throw as the SSA gets higher. That's just the way it works.
I was following you up to this example. What you're saying is that the rating for a player will be the same for these 2 situations: 1) someone throws 40 on a course whose SSA is 50, and 2) someone throws 80 on a course whose SSA is 100.
Shouldn't the latter score be a much more impressive feat, to throw that well for twice as long?
If it is more impressive, is that taken into account by weighting the round of 80 on a 100-SSA course when calculating average ratings?
For example, when averaging the ratings over several rounds, if these were the ratings:
1010 on a course of SSA 50, weight factor = 1.0
1080 on a course of SSA 100, weight factor = 2.0
average rating = 1010 * 1.0 + 1080 * 2.0 / (1.0 + 2.0)
average rating = 1056.7
Is this what is done now (or something similar)?
Edited to add: even that wouldn't weight the latter round any more if the earlier round was rated 1080 on a 50-SSA course. Then the average would just work out to be 1080, as if both rounds were of equal accomplishment. But being consistently good over a longer period of time is known to be more difficult, so it seems this should be taken into account in ratings. Is it?
So I've asked this question before and never got an answer to it. I think the next thing that they should do is work a "weighted round" into ratings. It is MUCH MORE impressive to shoot a 1050 rated round on a 27 hole course rather than a 18 hole course. You have to keep that play up for an extra 9 more holes, why shouldn't that be weighted 1.5 times as much? I believe ratings should be weighed based on 18, 24, and 27 hole rounds. In tournaments where you play an 18 hole round, then a 24 hole round, players who you end up beating over all in the tournament can end up having a higher rating average for the tournament, I don't see how you can say that is fair. Just because they shot 1 stroke better on the short course and you shot 2 strokes better on the long course . . .

You have named the only players who might benefit from a higher rating, as far as I can tell. The rating is a factor determining sponsorship, for a few elite players, but not a bonus.
The only reason I can see for wanting my own rating to be higher, is vanity. Same goes for most players who will never be on the tour and sponsored.
If the ratings were tied to handicaps, we would have even less reason to want a higher rating, I think.
Ratings are not an indication of skill level, just at what level, on average, we have been playing the rated tournaments: At least for someone like myself, who has a broad range of rating scores. My rating is somewhere in the middle of those scores But you don't know whether I will beat 1000+ rated players, as I did in the last two tourneys, or lose to 940 rated players as I did in several tournaments prior to that.
If I had a small range of scores, my rating would then be not only indicative of my playing level, but also my skill level too.
I do agree that the ratings seem, at times, to not reflect the skill levels present on any particular round, (for whatever reason). But, over several rounds, they do seem to catch the level at which we played, (if not the reason we played that way).
The ratings don't care if we had a sprained ankle or other illness or injury that we're playing through, or were up all night on a red eye, or hadn't had a chance to practice the course, or never play well in the cold and rain. The ratings only care how we did in relation to the others that played at the same time.
So, are ratings a true measure of skill level? Not necessarily, IMO. Are the ratings a good measure of average playing level? I think so.

Good call Dave,
I like a ranking system over the ratings as it would apply to the skill level by using more head to head rounds.
I have expressed the need for a ranking over and over again. I hope we develop one soon, as it should drive the competition among the players from coast to coast.
I know there is a world ranking but it is WAY off base and players should be required to play a minimum of events( a few more than 2) 60% of the A tiers and NT's would be a good place to start

You just described most statistics in most sports in existence.
Is a baseball player that goes 4/4 every third game (with 0/4 performances in the between games) better or worse than somebody that gives you two hits one night and then a hit on each of the other two nights? (how about Alex Rodriguez who bats .300 but never gets a hit in the clutch... is he a better or worse hitter than oh say Jim Thome who bats .290 but seems to perform when most needed?)
Is a basketball power forward that hits on 12 of 25 shots from the field one night, 20/23 the next, and 3/19 on the third any better than the fellow that drops in 13/20, 10/15, and 12/19?
Statistics are averages, they're not always going to be perfect, but they're good indicators of where somebody stands in general.

I think that for a player like you, a former World Champion, and someone who has been a pro for a long time and who knows experientially where his game is on a given day or tournament or time frame -- your rating may be less meaningful than to someone relatively new like myself who can watch his rating go up as he improves and becomes more experienced...

There is a not very well publicized frequent flyer mile program for high rated amateur men. That's why they are always fretting over whether they are 959 or 961.
Plus, if you walk into any bar in the United States and casually mention that you are an amateur with a rating over 960, suddenly you are surrounded with chicks. Works every time.

Don't 1000 rated players get a bumper sticker? "Disc Golf God" Also, if your rating is low enough it can engender sympathy and in the right setting, free beer.

Add up Hines' round scores (39,75,68,40) = 222.
Listed final score is 262.
TD made a little data entry error for the first round of the golfers in the final 9. Urm, that'd be my guess I should say.
Odd that each golfer's round sum is off by exactly what each shot in the final 9. Hrm...

If I shot a 1176 round in advanced and found out I was down 10 strokes, I would be a little uspet.

not to mention, shooting a 1100+ rated round generally DQs you from shooting MA-2... again.... EVER. Heck, my rating is around 913, but I've shot a 1000 rated round, and I'd feel bad shooting MA-2.

Late reply to this post...
Having just played a tourney where I was 'off', I realized that I knew what was off and know that the rounds will be below my rating/skill level representation. Having said that, I've also noticed that, as I've played in more tournaments and more league rounds, I know where I stand in skill and where I belong. I think you just took "Know what you throw, and throw what you know" to the next level and made it "Know how you're throwing what you know". More players should pay attention to where they feel they are and less to their rating.
