I was watching a 9.0 mixed match from the observation deck just to see what its like at that level. I didn't know the level when I first got there, and based on what I saw, I guessed they were only 4.0 players. I was not impressed by the women players, most of their serves had a pushing motion which is pretty common at the 3.X level. Their groundstrokes were not well developed either. The men had pretty strong serves and polished strokes, but not an overwhelming amount of pace as people on this board would suggest. I feel like this level of play would be pretty attainable by simply working on my consistency. I guess if I watched men's singles or doubles the game would be faster. I had a hard time believing that those women could beat me in a match though, but obviously if they are 4.5 they should.
