My wife plays almost entirely singles in 4.0 18+ and 40+ USTA leagues, and she wins about 4 of 5 matches. (Other captains often put a 3.5 player against her). Last year, due to Covid, she played only one match before the USTA (Southern in upstate SC) abandoned the season. Going into this season her UTR rating was 5.7. So far, she's won 2 of 3 singles matches and lost one dubs match. Nonetheless, her UTR has fallen to 2.0. I'm guessing this is because UTR calculates, among other factors, matches over the past 12 months and apparently has not modified their algorithm to account for a lack of matches in 2020 due to the pandemic (which I understand). Obviously, this is a clear first-world problem which does not concern her too much. Has anyone else experienced this? Curious to hear comments.
