How Your Rating Works
The Universal Badminton Rating uses an ELO-inspired algorithm similar to those in chess, tennis, and other competitive sports, but with one important twist: rating changes are based on expected outcome, not just win or loss.
For example, if a 5,000 rated player loses 21-19 to a 7,000 rated player, their rating will still go up. They were expected to lose 21-10 against a much stronger opponent, so keeping the score that close is over-performance. In our mixers and events we show a target graphic on every match so you can see exactly what your expected outcome looks like before you play.
UBR also calculates a separate tournament rating using a 10-game rolling average. This prevents players from sandbagging their main rating to slip into lower divisions at big tournaments, your tournament rating reflects how you have actually been playing recently.
We maintain separate ratings for singles and doubles, because your ability in each format can be quite different. This gives you an accurate picture of your skill in both disciplines.
