There weren't a lot of changes for the teams that I am on. A few of the 4.0 teams that we play against had a few guys bumped down, which means I will probably start seeing them in my 3.5 team matches. I play in two different 3.5 leagues (different regions and age levels) and I found only 3 players bumped up from 3.5 to 4.0 across both flights. Even a guy who went a combined 10-1 in 2020 and 2021 didn't make it.
On the ladies' side, there's an egregious cheater who self rated at 3.0 in 2019, appealed or was DQed to 3.5C in 2020, and was handing out bagels and breadsticks in the 4.0 league for the past 2 years playing "up" as a 3.5. She has a combined 46-3 record since joining USTA. Well she's now a 4.0C, so I guess she can take home another 20 or so lopsided wins this year before ending up as a 4.5C where she belongs.
Ratings this year were kind of boring honestly given that we had 2 years of matches to go on.
