I don't think I'd believe it if you showed me a video.

Cubby can show you lots of his aces online...

Statistically, what is the probability of three pros, rated 966, 936, and 967 finishing 2nd, 3rd, and 5th respectively in intermediate (had they been able to play that division) where the highest rated player on that day was 904?

[JohnLambert]

I'm just trying to grasp how our #1 rated player in the world is an AM2 guy who played a 9 hole course (twice through).

[pdorries]

im still listed on the Oklahoma Am Men list, and i took some cashhhh. you can change my status if thats possible

accepted the cash at 10,000 challenge

[DSproAVIAR]

That is the case with 7-10 rookies from Michigan as well.

I really like the rating system the PDGA uses and I think it works very well. I do have two questions on how the formula is calculated. If the last 25% rounds are double weighted and I have 22 rounds, then 5.5 rounds would be double weighted? (22 rounds * 25% = 5.5 rounds). Would I still include the 6th round but only count .5 of it, and then for the total rounds used would be 27.5 rounds (22 rounds + 5.5 double weighted). Just want to make sure my math is correct. I did use this method and got the correct rating calculated.

Hi Chuck--Did the am ratings update happen as well? My rating did not get updated yesterday. played 2 tourneys since last update. are the am updates just running behind?
thanks

Not out of the question for 27 holes. I see Intermediates beat pros all the time at leagues. This was a new course that hadn't been played before in PDGA so I'm not sure how well the pros knew the layout. If it was really wooded, it could have had a lot of lumber hit.

It's possible to be listed on both the Am and Pro Points and Money lists if you play in both during the year. Your points earned in pro are tracked separately from those earned in Am divisions. However, at the end of the year, your official status as an Am or Pro will determine which list will count for Worlds invites and toruing pin awards. I've got points in both for example since I've entered Advanced, Adv Master, Open, Master Pro and GM Pro during this year.

Everyone's rating always gets updated every time we do ratings. But if you don't have any new events that have been officially reported, then your date doesn't change.

[cgkdisc]

We're looking into a problem where it appears that anyone who played in the Steady Ed Birthday Memorial did not have their rounds included in their rating even though they show up on their Ratings Detail list.

[spudpicker]

Hi Chuck,
Curious about the first round rating of the Farragut Open...Pro Men played a different layout on two of the holes adding about 350 total extra feet to the course (and challenge) then the rest of the field....yet a 55 in open division was a 897 rated round and a 55 in all other divisions was a 933...any particular reason for this?

[cgkdisc]

I've asked Roger to check into this. Doing things like special tees for only a small number of players is always risky because it reduces the number of propagators for each group and raises the chance for statistically less probable anomalies like this one.

[spudpicker]

Alot of us tried to mention this to the TD...to no avail, i believe hte whole prblem could have been resolved by simply allowing the AM1 division to play the same course thus increasing the amount of players eligiblae for ratings with the layout.
Thanks for the response...i couls understand i slight rating flux one way or the other, but 36 point difference seemed a bit of a large spread.

Chuck,

Please explain about the "Touring Pin awards."

I'm 100 points away from leading my state in points. Will I receive anything for being the points winner, if that happens?

Thanks in advance.

[cgkdisc]

Not sure how it works in terms of who and how many get awards. Contact the PDGA office at: tourmgr@pdga.com

[jarmiller]

Thanks. I just did. I was curious since I heard the PDGA got rid of the pins last year.

Hey Chuck,

My wife has been playing open all year. We are playing a tournament this weekend where there is no Open Female division what so ever. So, under the Pros playing Am format she has decided to play Advanced Male. From what I've read it doesn't state whether or not she can accept prizes if she places. My question is, If she does place, can she accept prizes even though shes considered a pro?

Thanks Chuck!!!

[cgkdisc]

Yes. Pros qualified by rating to enter an Am division qualify for the same merch prizes that Ams can win if they "cash." Wish her luck for me.

[bruce_brakel]

She could also play in the amateur division indicated by her rating, if it is being offered.

[DSproAVIAR]

Chuck,

I'm wondering how I can calculate whether or not a recent rated round will count towards my rating. The round was rated slightly less than 100 pts below my rating, but I'm looking for a formula to try and calculate the 2.5xSD thing.

I'm just looking for a formula and I'll do the work, but for specific info-

Here's my ratings detail:

http://www.pdga.com/player-ratings-d...how_excluded=1

and the round was unofficially rated 892. Let's assume that's the official rating as well.

Thanks!

[cgkdisc]

Put all of your ratings in a column of an Excel spreadsheet and activate the Standard Deviation function on it. That will give you the SD. Multiply that value by 2.5 which should get you reasonably close.

[DSproAVIAR]

Sweet, 2.5SD=80.9, so is it correct that all rounds over 81 points below my rating will be dropped?

Thanks again.

[bruce_brakel]

Oh, speaking of ratings, do you think you can do something manually with the USWDGC amateur pool so that the amateur women get ratings? Maybe include 700+ Intermediate women as gatorettes or something? I noticed that they did not have enough gatorettes for unofficial ratings but did not take the time to check every one to see if there were enogh for official ratings.

[cgkdisc]

John Resch already posted that we're on top of doing official ratings by Oct 20th for all who attended USWDGC.

Sweet, 2.5SD=80.9, so is it correct that all rounds over 81 points below my rating will be dropped?

That's assuming the unofficial round ratings included in your rating for the next update stay the same once official and rounds don't drop off of your calculation changing your SD.

Hi Chuck,

Im running a Super Class event in a few weeks and am curious how the ratings work for this? How would I figure the rating for what would make a 1000 rated round at Camden 2? Thanks, and sorry because Im sure its posted elsewhere.

Hi Chuck,

I was wondering if you could take a look at a tournament's ratings for me.

http://www.pdga.com/tournament-resul...ratings=1#Open

The tournament took place on a relatively simple 18 holes at about 4400 feet. The ratings seem off to me as -13 was needed for a 1000 rated round. I know of a course (Knollwood Park) in Kalamazoo from my memory was a 42 SSA. This course we played is not easier than Knollwood. Do you foresee these ratings changing when they get processed for the 10/20 ratings release?

I understand that a course like this likely messes with the system a bit, but needing -14 to surpass the SSA threshold is mean

We don't yet know how to estimate the SC course rating ahead of time. Although it looks like the SCA is about 5 throws higher than the SSA if it's a course suitable for Super Class. We calculate the course SCA (Super Class Average) the same way as the SSA using the scores and regular PDGA ratings of the propagators who enter. Pete Hazen (MN) and I are the only SC propagators in the world so far with at least 8 rated SC rounds.

Looks like the results have gone official so I can't see ratings until we process them. A course with a 41.4 SSA is officially the lowest we can consider for viable ratings. Even then, each throw is worth more than any other course which means an OB, cut thru or spit hurts more. Regardless, we've determined that players can still average their rating on these courses, but they might not have as high or as low deviations from their rating as on courses in the 50 range.

I wonder what percentage of members think that SC is a good idea.
