I just started playing in a flex league this year. I don't like the user interface because its too limited. I can't even browse flex leagues outside of my own flight. Anyways I've played one match in my 4.0 flex league. I beat the guy pretty easily. I would rate him as a low-mid 3.5 at best...very different than what I've experienced in real usta league play where I went 1-8 and spent most of the time getting crushed. Also I noticed one of the players in my flight is a 4.5 rated player. Whats even more odd is that he played usta adult league the last couple years, yet he is self-rated?!? Anyone have any thoughts or experiences involving flex leagues?
