I've only been playing USTA for a year now, and when I signed up, the computer rated me as 3.5C but I'm actually a strong 4.0. I've been playing in 4.0 leagues and winning the majority of my matches. I should finish the season with a winning record... is this enough to bump up my rating to 4.0? I noticed that other players, for example, had two seasons in a row undefeated... 9 wins 0 losses, and yet they remained the same rating. What does it take to move up?
