Ask Chuck Kennedy

[Zbrock]

A. Chuck were the ratings updated yesterday?
B. If they were why was my rating not updated, I have played seven rounds since the last update.

Thanks

Just playing the rounds doesn't mean your rating will be updated if the TDs for those events didn't turn in their reports by the May 5th deadline to get processed. TDs have 30 days to turn in reports so in some cases, they may not have been late. TDs who are late get regular notices from the PDGA to get reports turned in.

Thank you for taking the time to answer questions, it is greatly appreciated. Here is a scenario that happened to my friend recently. He recently joined the PDGA and then entered a PDGA B tier event. The event happened about 8 days before the TD report deadline (MAY 5th). He shot a 998, 856, and 942 rated rounds. The TD apparently didn't turn the report in on time. First question: Had the TD reported it on time would the 100 pt below rule drop the 856, so his rating would be around 970? Question 2: If the TD reports it by the next update deadline will those ratings still be used? I remember reading somewhere that the TD has to report it in a timely fashion or they won't count. Again thank you for your time and happy golfing.

hey chuck,
for events immediately following an update such as this week's virginia open stuff what is the rule for players whose rating has risen out of the division they registered for?

[cgkdisc]

A TD missing the deadline only means the rounds won't get processed in that update. But they will get processed for everyone who played in that event once the report gets turned in.

For new players, we don't drop any rounds until they have played at least 8 because we really don't know what's "normal" for them yet. So that 856 will likely count toward that player's rating unless he plays more before the next update and has at least 8 rounds to consider that average above 956.

Players have a 2-week grace period following the ratings update to remain in the division they pre-registered for as long as they did it before the ratings were posted. Once the ratings are posted, TDs of events within 2 weeks afterward have the option to allow players to enter the division of their old rating or they can require them to enter their new division. TD choice.

. TDs who are late get regular notices from the PDGA to get reports turned in.

Is this something new? It doesn't seem like this has happened in the recent past....

[cgkdisc]

That's the policy. Not sure how well executed since my reports haven't been late to test their procedure. I can say though that for the past several years now, all reports for a year have eventually gotten done in time for the yearend ratings. Several TDs took up lots of PDGA office time contacting them by phone and email to complete the reports.

[pdorries]

will we see an amendment to the last update for the glass blown open ratings or should we just expect to see the change in the next official update?

[cgkdisc]

There will be a correction run to deal with Glass Blown and a few other items to be posted in mid-June.

Chuck,

Can you tell me why when I'm in the state of Georgia do I throw ~1000 rated rounds only when it doesn't matter?

I don't seem to have this problem in other states where I usually will make money shooting 1000 rated rounds.

[krazybronco]

ok i know these rounds are not offical but i had a question about them anyways

ok during the Hall of Fame classic this weekend the advanced and open player that shot the same score on the jim warner course had a ratting higher than the MA2/MA3 people that also had the same score

for the first round MA1 played the warner course then open players play the same course the second round and MA2/MA3 played the third round
http://www.pdga.com/tournament-results?TournID=8592

i was wonding how there can be an almost twenty point swing when the weather was pretty much the same the whole weekend

[cgkdisc]

We now combine all scores from all rounds played on the same layout to calculate official ratings unless the weather is different. So everyone who played the Warner will end up with the same rating for the same score. Same thing for Headrick and Jackson. The software for the unofficial online calculations wasn't programmed to combine rounds on the same layout so you see the differences.

As a general note, the higher the rating of the player pool, the more accurately ratings are produced because the range of their scores are tighter and more consistent. Even though 20 points seems like a lot, it's less than 4% variance from the higher rated pools.

[krupicka]

The higher rated pools also tend to have less players that are underrated. Rapidly improving players can depress ratings.

ok it was just kind of a surpise when i see the round ratings at the IDGC and see that my 68 was rated lower than a 70 the day before on the same course

but your saying is most of the round ratings will change with at least one round being higher

[cgkdisc]

Now it could have been that the Hall of Famers playing it Saturday left a lot of good karma out there for your divisions and the course played two throws easier...

I think i might have had to much karma for that course with the hall of famers, helping put in all the tee signs and got a little from feldberg with him telling me i was going to putt well but a 940 round rating would be really nice

but thanks for the expliantions

[mitchjustice]

Chuck...what is the highest rating that a player has started with?...we have a local with 1009 as his first player rating....of course it will be lower than 1000 after the next update

[cgkdisc]

We don't really track that info. However, when we calculated the first ratings after the 1998 Worlds, Climo "started" with a 1032.

[bruce_brakel]

The mathematical effect identified by Krupicka is probably more significant than the one identified by Chuck, and probably more likely to explain the difference at this tournament.

You can see the same ratings skewing effect in rounds 1 and 2 of the Stateline this past weekend, comparing the ProAdv pool to the Int pool. Par averaged 932 for the lower pool and 950 for the upper pool. Same courses, and over two rounds, same average conditions.

[cgkdisc]

We are looking into the possibility of selecting props to use for a round based on their standard deviations rather than rating. If we have enough props (30+?) with SD under say 30, then we won't use props with SD over 30. We would only use the higher SD props when needed for rounds where we had fewer than 30 total props. This should reduce the differences we might see in official ratings and account for the under rated up-and-comers depressing numbers. But it still wouldn't be programmed into the online unofficial process, at least for a while.

Even though Chuck didn't answer my question, I'll help him out with yours.

The MA2/3 were supposed to play the shorter tees on the Warner course, acccording to what Jason said on Saturday morning - so if they did that might account for it. I personally don't know if it stayed that way or if they played longer tees as I was to busy figuring out a way to get a throw through 80 foot wide openings, after last week not having too much trouble getting the discs through only 12 foot wide openings.

[cgkdisc]

If they did play a shorter layout, Jason did not enter a separate course layout to use for calculating their unofficial ratings.

[keithjohnson]

They may have all played same pads in the C pool, as I said I wasn't really worrying about them, even though I was playing worse than an AM3.

[sunrisensunrise]

I noticed the unofficial ratings changed for the Summertime Open but the total under/over par hasn't. The upper course was par 60 and the lower course was par 54. Both courses were played twice by all players from the same tees. Would the official ratings possibly end up being higher because of this?

[cgkdisc]

If the Unofficial ratings are not done properly then it's very likely the Official ratings will be different. Different par values won't make any difference as long as the correct number of holes was entered for each course.

The results/ratings for Summertime Open have now been updated. Each division should now be showing the proper (unofficial) ratings for the courses they played.

Pool A played Round 1 on the Upper course, Round 2 Lower, Round 3 Lower, Round 4 Upper and Pool B played opposite.

Pool A consisted of Open, Open Women, Advanced Men, Advanced Women and Intermediate Men. All other divisions played in Pool B.

[33009]

is there a page on this website that will tell me how round rating are calculated and what it takes to (#of rounds etc.) to make your rating rise.

I think my problem is that i joined the PDGA when i was a newbie and i started off in the 800's, now im finally a 912, my last 6 rounds have been a BSF 949,939,880(ouch) 914,939,911. i did the math by adding all together and dividing by 6 and come up with a 922. so does this mean my rating should go up a little, or do other past rounds have to drop off before.

Confused in Boise......
