You may recall a recent Pickleblog from May 22, 2025, entitled, “Understanding DUPR.” However, much has changed since then. In early July 2025, DUPR Inc. released an update to its Dynamic Universal Pickleball Ratings (DUPR) algorithm so that now, DUPR ratings adjust based on a player’s performance compared to his/her expected score.
Starting July 8, 2025, a player’s rating changes based on how he/she performs relative to how he/she was expected to perform in a given match, not on whether he/she wins or loses a game. DUPR assigns every match an expected score before it is played, based on the ratings of the players involved. If you score more points than expected, your rating will go up, even if you lose. If you score less than expected, however, your rating will go down, even if you win. Under the prior algorithm, the winning team’s rating would always go up and the losing team’s rating would always go down.
According to DUPR’s website, its algorithm takes four primary components into account when calculating a player’s ranking:
- Performance vs. Expectation: Each match has an expected score that is based on player ratings. If a player scores more points than expected, his/her rating will go up. If he/she scores fewer points than expected, his/her rating will go down.
- Type of Match: A club or tournament match influences a player’s rating more than a self-posted one.
- Match Recency: Newer matches have a larger impact on a player’s rating than older ones.
- Match Volume: Each match refines a player’s rating. More match history leads to more stable and accurate ratings.
