On your player profile, you may see matches that do not have a tennis ball next to them, even though they're less than 12 months/30 matches old. Why?
The algorithm excludes matches in which:
- A player withdraws before the match starts
- The match starts but neither player wins at least four games (due to a withdrawal/retirement)
- There is a UTR difference of more than 2.50 and the higher-rated player wins as expected. These excluded matches still show up on the player profile but are not used in the rating calculation.
