I think I broke the USTA Code for at least a portion this year's bumps. In my area, 64 3.5 Men played both 3.5 and 4.0. 37 (57.8%) of the 64 were bumped, while 27 (42%) remained at 3.5. But it gets more interesting. My theory is the the USTA awards more Dynamic Rating Points for playing up than winning (unless winning decisively) at your current level. Wins at current level (unless the margin of victory is dominate in the 1-1, 2-2 range, don't do much to a rating. I looked at a few other players from our area, notably one player who played #1 Singles, went to the local playoffs and has a "B" rating. I also looked at guys who played both 3.5 and played up at 4.0. One guy played both 3.5 and 4.0 in the Adult and Senior Leagues. The #1 Single's Player went 14-2, went to playoffs and now has a "B" Rating. The only loses were to two players who were bumped to 4.0. One of the losses was to a 3.5 "S" player who was DQ'd player, so his record actually went to 15-1. Only one of his wins went to three sets. His matches that counted toward his year-end rating: 7 Wins: 0&5, 4&1, 1&4, 1&1, 3&4, 2-2, 3-6/6-3/6-4 1 Loss: 3&1 (to a player who was bumped) Then he had one loss that doesn't affect his Dynamic Rating against a 3.5 "S" who was DQed). (4-6, 6-2, 6-1) He was unbeaten in 7 matches this fall, all in straight sets. He didn't get bumped. Why I think I'm right: We had two guys from my Men's 3.5 Team bumped to 4.0. Neither were self-rated players. One guy is clearly dominate at 3.5 in Singles, and wins consistently when playing 4.0 Doubles, and beats 4.0 players in Singles Leagues as well. The other guy is a solid doubles players, and only played at 4.0 in the Spring. His record was 1-4, but all the matches were either 3 sets or 7-5, 6-4 The Singles's Player who went 14-2 DID NOT play both 3.5 and 4.0 Know compare this dominate Single's player who only played Men's 3.5, to a Senior 3.5 Man, who played both Adult and Senior 4.0 and Adult 3.5, and Senior 4.0 The Senior Guy's spring record was: 0-6 Spring Senior Adult 4.0s (Lost 3&2 twice, 3&1 twice, 1&1, and 5-4) 1-4 Spring Adult 4.0 (Lost 4&3, 5&4, 1-6/6-4/6-1, 6-4/3-6/7-6, Won 4&2) 2-0 Spring Adult 3.5 (Won 3-6/6-3/6-4, and 4&2) 3-10 Combined Record for matches that count toward his year-end rating. And yes, he was bumped to 4.0. If you add in his Fall 3.5 record of 0-5, he went 3-15 for the year. This doesn't make much sense to me mathematically, but hey, it's the USTA. :-? To be bumped up, simply play up. If the matches are close, you're likely to be bumped. 57.8 % of the guys who played up in my area were bumped. The best part: The guy who went 15-1 as a single's player and had a team record of 17-0, only lost one guy. Nice guys with a killer team. He played three matches and beat another guy who was bumped who played both 3.5 & 4.0.
