The singles and doubles algorithms are very similar. For doubles, the algorithm compares the average UTR Rating of Team A to the average UTR Rating of Team B. Given the UTR Rating difference between those two averages, the algorithm expects a certain percentage of games won. The team that performs better than the algorithm’s expectation will see their match rating go up. Both teammates see an increase or decrease by the same amount.
