We’ve made an important update to the DUPR rating algorithm. Starting today, your rating will move based on how you’re actually performing—not whether you win or lose.
What’s Changed?
Your rating now moves based on performance vs. expectation.
Every match has an expected score, calculated from the ratings of the players involved.
If you score more than expected, your DUPR rating will go up - even if you lose. If you score less, it will go down - even if you win.
Whereas before, the winning team would always go up and the losing team would go down.
Doubles Example:
If a team is expected to win 11–3 but wins 11–8, their DUPR rating will go down.
The losing team, which was expected to score fewer points, will go up.
Singles Example:
If you’re a 3.5 playing against a 4.0, we expect the score to be 5-11. If you instead lose 9-11, you’ve overperformed expectations, so you will see your rating go up.
What this recent update solves for
✅ Performance-based
Your rating now reflects how you perform relative to expectations — not whether you win or lose. Every point matters.
✅ More accurate
By going deeper into point-level performance, DUPR delivers a more precise measure of your current skill level.
✅ Fair for everyone
Every player has a chance to improve their rating by overperforming — whether you're the favorite or the underdog.
Bottom line: every point counts. Whether you’re the underdog or the favorite, the algorithm rewards players who perform above expectations. Even if you lose, proving you can compete at a higher level will improve your DUPR rating.
As the rating of the sport, we are committed to constantly improving rating accuracy and player experience — this update shows our continued focus on delivering that commitment.
