Do some matches not count towards my UTR?
The algorithm excludes matches in which a) a player withdraws before the match starts, b) the match starts but neither player wins at least four games (due to a withdrawal/retirement), or c) there is a UTR difference of more than 2.00 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.
