Ask Chuck Kennedy

[JenniferB]

Hey, Bruce! Actually, Chuck called the TD and let him know about the skins not counting as prize money. Thanks, Chuck! You're awesome!

I did play skins and we won $500. I'm trying to figure out what to do with my half. I want to put it back into the game in some way. I've contacted a local player about helping to sponsor her for am worlds, and if she can't make it, I'm sure there are plenty of other options. Maybe I'll donate it as added cash for the ladies pro payout at next year's tournament, so they can attract some real talent for the skins match next year.

Chuck, the ratings for Disc'o de Mayo (http://www.pdga.com/tournament_results/67389) are incorrect due to layout differences. I've contacted the TD multiple times, and his responses, dating back to May 8 or so, was "the PDGA is working on it". Any idea what the status is on this?

Advanced: played long-long
Intermediate: played short-long
Rec & Adv Women: played short-short

As it stands, all the scores are showing up against the same layout, bumping up ratings for Ints in round 1, and Rec & Adv Women, while bumping down ratings for Advanced.

[cgkdisc]

Those ratings are unofficial based on what the TD posted. The official ratings will likely be correct because the TD will send the report to the PDGA with the proper course layouts so the ratings can be done properly. The TD is the only one who can correct those unofficial ratings.

Ck fellow Minnesota frisbee association member. Sorry gotta plug my Club. My 1st post on the pdga board here hope that it doesn't get me in trouble. I'd like to ask you a question. When I search my player statistics I'm only showing 1 event played yet I have 5. Do events only show after they are included in the players rating update? Or after the td submits them to the pdga? Thanks chuck.

A player's events will show on the site if the TD posts them and you'll see unofficial ratings. These scores and ratings will not show up in your player stats. Once the TD sends the report into the PDGA, your official scores will be posted but not ratings. Then, the official ratings will show up at the next ratings update. So if you have four events without stats, the TDs have either not yet sent the reports to the PDGA or the PDGA has them and hasn't posted them yet.

Chuck,
Will the Aspens Sports Treebash Open (June 4 & 5) be included in the next update?
Thanks

[cgkdisc]

I don't know. I haven't gotten the reports from PDGA HQ for processing the course layouts yet. Once you see the results online posted as "Official" you know it will be processed.

Hey Chuck,

Do you know where I can find that picture of all the discs hanging on the basket, that explains what is "good" or "no good"?

Thanks,

Chris

Chuck,

I can't find info on course ssa's. This doesn't seem to work.

[907miller]

curious why ratings are the same for all 3 days when the weather/scores were worse on day 1? thanks.

[cgkdisc]

If the daily SSAs do not deviate more than what would be expected from normal statistical variance, all of the rounds are averaged so everyone gets the same rating for the same score in all rounds. From a practical standpoint, it doesn't matter because a player's overall average rating for the three rounds will be the same whether each round is rated separately or combined the way it's normally done.

That being said, having been at the event, I'll take a look because I expected R1 to be rated separately.

[JenniferB]

Chuck,

I recall that you indicated the PDGA stores ratings on a per hole basis (i.e., 18 ratings of 1000 for a 1000 rated round on an 18 hole course). Do I have that correct?

Additionally, when the most recent 25% of rounds are counted twice, does the process retrieve the most recent 25% of holes, or does it select whole rounds only? If whole rounds, how is the number of rounds to be used determined if there are an odd number of holes? For example, if there are 14 rounds total, do you double the most recent 4 rounds or the most recent 5 rounds?

For tournaments of multiple rounds, are these are all considered played on the same day, and the highest ratings taken first to fulfill the 25% allotment?

If the average comes out to a decimal value, does it get rounded off, or is there a ceiling or floor function?

Are you still throwing out the lowest round when determining SD? If so, is the whole round worth of hole ratings ignored, regardless of the number of holes? If not, how is SD calculated and lower ratings dropped?

Thanks

[cgkdisc]

Yes, on the per hole basis. Whole rounds only and your better rated rounds are used if only some will be doubled. Ratings are truncated so you have to actually hit 1000 rating not just 999.5 and get rounded up. That's all I'll answer. Some of the details are kept under wraps in a moderate effort to reduce ratings manipulation which is being attempted by some players unfortunately.

Regarding: "if there are 14 rounds total, do you double the most recent 3 rounds or the most recent 4 rounds?"

... is that one of the details you mean to keep under wraps, or did you overlook that one?

[cgkdisc]

Yes.

D-Board hiatus. Rather than post your questions here for the next several weeks, please contact me at my PDGA email: ratings@pdga.com and I'll try to answer them.

[the_kid]

So how does someone's rating go down without any new rounds entered? I know you have covered this before just don't remember the answer.

[terrorlax]

i have played in four tournaments since the last rating updates. why didn't they show up after the most recent update (6/21/11)

[ERicJ]

One way is if you had highly rated rounds that are now older than the 12 month cutoff as of the most recent update, so they fall off your average calculation.

[krupicka]

Not true. If you don't have any new rounds, you won't drop old rounds. The 12 month cut-off is based off your most recent officially rated round, not the date of the ratings cutoff.

The more likely explanation is either a) a rating correction to an existing event, or b) an old event finally going official (you might not notice it if it is not recent).

[jimimc]

I know you've answered this before, but I can't find it and don't get it. Which rounds are excluded from your ratings and why. In the past year I have had rounds as high as 950 excluded and rounds as low as 923 included. I've had as many as three rounds excluded and as few as one excluded while my rounds played pretty much remained the same. My rating remains consistently in the 980's even when I think it would go up or down.

[jobwilson]

Here is my question regarding 7/12 update.

Why is an event that was played on 6/25-26 not included in this most recent update? (Evansville Open)

It was a B-Tier and scores were inputted in real-time.

Thanks

[cgkdisc]

@ jimimc - The process is automated and simply makes decisions based on how consistent your rounds were that are in your current rating. If they fall outside 2.5 standard deviations below your straight rating average, they are excluded for that update.

@ jobwilson - Seeing results online is separate from the PDGA receiving the official TD report. TDs can post your scores even during the event and you'll see unofficial ratings. But that doesn't mean the PDGA has the TD report yet which includes important information needed to process the ratings such as correct course layouts and membership information for renewals and new members. The TD did not get the report to the PDGA by the June 28th deadline for this 7/12 update.

[bruce_brakel]

Chuck, for the past ten years Kelsey's rating http://www.pdga.com/player_ratings_d...778/2011/16007 has been lower than mine http://www.pdga.com/player_stats/26655/2011 and I've always paid her entry fees. Starting with the next ratings update, do you think it would be fair if she started paying my entry fee?

[bruce_brakel]

Stumped for the clever rejoinder? More seriously then, is a World Rankings update coming out shortly? I've been trying to get Kelsey to B-tiers and A-tiers so she can get in enough rounds to stay on the list.

Also, can you comment on the POY controversy or would that be impolitic? I understand if it is the latter. I was just curious where the ambiguity krept up in the objective standards. The minutes make it sound like maybe it was an (A + B) / C does not equal A + (B / C) thing.

[cgkdisc]

There will be a World Ranking update by next week based on the latest rating update. I don't know what is going on with POY. The Board is discussing which "objective standards" should be used. We likely won't post any 2011 POY/ROY standings until after Worlds when there will be enough events in the books.

[bruce_brakel]

One last question for now --this came up

this weekend at a tournament: at a split

weekend tournament where some

divisions play Saturday and some play

Sunday, and all play the same course

configurations, are the two days

combined for calculating ratings? Type

your answer really big because Keith

Aten is legally blind.

[cgkdisc]

It's a good question. Because they are separate events and imported independently for ratings, I suspect they are rated separately. I'm checking with Roger to confirm.
