The singles and doubles algorithms are very similar. For doubles, the algorithm compares the average UTR of Team A to the average UTR of Team B. Given the UTR difference between those two averages, the algorithm expects a certain percent of games won. The team who 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.
