DUPR FAQs

Do I have to link with DUPR? Linking with DUPR is optional for Pictona membership. We are planning future events where results will be submitted to DUPR. For those events, if you already have a DUPR account, we will link to it. If you don't have an account, one will be created for you when we submit the scores.

Why does my DUPR profile say NR? NR means “Not rated.” It likely means that no match scores have been submitted yet.

Why is there an asterisk next to my rating in DUPR? The asterisk means that your rating is “provisional.” When you submit more games scores, your rating will become more accurate and the asterisk will be removed by DUPR.

Why does DUPR matter? Accurate player ratings assure that players who enter tournaments at a specific skill category truly play at that level, which leads to more competitive and fair games.

How is DUPR different than UTPR? UTPR is only available to players who are USA Pickleball members and who play in tournaments. DUPR is available to anyone and can be used to report tournament, league, club, open play or recreational matches. Additionally, the UTPR calculates player ratings based on wins and losses. The DUPR algorithm factors in the game score, so players that lose a match 11-9 would be weighted differently that players who lose 11-0.

How are DUPR self-reported scores different than club-reported game scores? Because the club scores are submitted by club directors, DUPR weighs these matches 5 times more than self-reported scores. The extra weight allows players to advance to a reliable skill rating in 5 to 10 games rather than a dozen or so self-reported games.

What is "Half Life?" Half Life is based on the principle of exponential decay and measures how many matches you’ve played and how recent they are. Players need 3 results in the last 90 days, 6 results in the last 180 days or 12 results in the last 270 days. In other words, the number of results needed to be fully reliable doubles every 90 days.

Why did my DUPR go down when I won? The algorithm has an EV (expected value) of performance in every match that you play. If the EV is that you win 11-5, 11-5 but you win 11-9, 11-9, it’s conceivable that your DUPR may go down. However, DUPR also looks at the performance of all players in the pool. For example, if the opponent against whom you just won 11-9, 11-9 performs equally well if not better in their subsequent matches, consistently beating the algorithm’s EV, their DUPR will increase but yours may not be as affected. Your opponent is obviously improving, and the algorithm “sees” that. 

Can my DUPR change even though I haven’t been playing? Absolutely. Just because you’ve stopped playing doesn’t mean the broader “pool” of players has stopped. For example, if you outperform the EV of the algorithm against a player and then she proceeds to also outperform the EV of the algorithm in her subsequent matches, you would benefit from her performance–even if you had stopped playing. 

What is the DUPR Reliability Score? The Reliability Score is a totally unique component of the DUPR algorithm that increases as a player:

  • Enters more DUPR results 
  • Plays with different partners
  • Plays against different opponents
  • Plays in DUPR certified leagues/tournaments
