I felt that everyone here is speaking another language as I have no idea
about the customs of being in a USTA team.
I'm in a team myself, but don't really care about being 4.5 or 5.0 or any of that crap.
Everyone across the court from me will be treated and respected as an worthy opponent regardless of skill. If your bad, your loss will be swift. If your good, your loss with be tedious and painful.
