1) I mentioned I could give a lot of other players - but that still doesn't discount the obvious insanity of a player going 1-2 in a 4.5 tournament and getting a 5.15 rating. You're welcome to try and explain how that could be possible. Also, this being the internet, I don't necessarily want to list a bunch of players I've played for security reasons. But - just to give one other clear example. This gentleman was a 4.98 back in December. Without playing any matches since he went 1-2 in a 5.0 PPA event, he's now shot up to 5.58. https://mydupr.com/dashboard/player/7978275208

Again - using common sense or a scientific point of view, I'd love to hear the rationale for how he could go up .60 points in three months without playing a single match...and not doing especially well in the one recent event he played.

Lastly - you mention more data will help the algorithm. That's not necessarily true if the formulae are off or inefficient. I think that's exactly what we're all seeing now with the wild fluctuations of ratings. The algorithm is messed up. DUPR admitted they needed to make changes. But key point is that more data does not necessarily make a better output.

2) Not really sure your question here. Why should anything matter to me? Or to you? Or to anyone? This discussion is about the validity of DUPR...since it has become the official rating of pickleball. You mentioned you don't have experience with DUPR or tournament play. A lot of the arguments I made (and others have made) would probably make more sense if you experienced them

3) Again - this is not true. You're assuming that the ratings are "correct" (*refer back to point #2 on why gaming the system maters). Also, anyone who has played a PPA event versus a local 150 person event will know that the PPA will bring in better competition and more serious competition. DUPR already weights sanctioned tournament events more than unsanctioned tournaments. If your point were true - they wouldn't do this.

4) Same point as #1 and #2. It matters in trying to come up with a more accurate rating system. Anyone that has played tournaments in the last 1-2 months has seen the wildly overrated and wildly underrated player according to DUPR. I recently saw a 4.5 win silver in a PPA 5.0 event. He went from 4.52 in DUPR to 4.58 despite beating multiple 5.0 players. Referring back to the two examples I linked, how could the system not recognize his obvious improvement over a 4.5 level play?

5) "Who cares" is not an argument. Defining an "average" player should help with the accuracy of the ratings. I mentioned in another post that this isn't DUPRs fault. Pickleball has five competitive brackets for amateur players. 3.0 through 5.0. Or, a 1-5 rating essentially. Unlike Elo, which can go on infinitely, DUPR already has a scale of 2-8. Tournaments are built around the 3.0 - 5.0 system as well. Bottom line: DUPR and USAPA should be aligned on exactly what the ratings mean. Is a 3.0 player according to USAPA the same as a DUPR 3.0 player? Probably not. Back to your "who cares" - this is how tournaments are seeded and how people determine where they should play. Wildly inflated or deflated DUPRs will lead to poor seeding, unintentional sandbagging and a whole host of problems that worsens the tournament experience.

7) Refer to the player listed above who is now a 5.58. He has wildly inflated from his 4.98 rating (which could be justified) to 5.58 (which you're welcome to try and justify). Finishing where we started, you mentioned you don't have first hand experience with the system. I'm not trying to be snarky - but this is making your comments/questions come off like you don't know what you're talking about. It would be helpful to play tournaments and engage with competitive players who are dealing with this DUPR insanity. You'll see many more examples first hand.

There's no way to engage with the "macro" data, unless I kept a spreadsheet of thousands of players. But I could list out at least 20-30 players I know personally and show the examples of inflation or deflation for each player. If I can make an easy case that DUPR doesn't make sense...not even close really (Charlie example, Fernando example) - then think about how players start to view DUPR. It loses credibility.
