so since ive taken up tennis again last year ive been playing singles and doubles. i just joined usta and plan on playing some tournaments. i play quite a few computer rated tournament players for fun. against 3.5s im beating them double bagels or 1 and 1. (4 guys) against 4.0s im winning 2 and 2, 3 and 0, 1 and 1 (3 guys) against 4.5s from 3 guys the scores have been : 2 and 2, 2 and 4, 3 and 0. this was on a mixure of hard court and hard tru over the past 4 months. all the games were tough for me. i didnt feel anyone game was harder to play they were all tough. i fought for every point and was trying to stay composed on all the matches. if i start playing usta should i play at 4.5 level or should i play the open tourneys? im a pretty good player but i always feel like i am on the verge of losing the game even when i am winning. i think i can do the opens because the guys i have played and beat pretty handily score wise are all regular tourney players. how good are the open guys? are they all ex college guys? (i am one) im in the nyc, nj area.
