Hi, new poster here, and first of all, really love the game!
However, I want to confirm something. If it's how it's intended, then it's fine.
I play on professional 10 (World tour, offline, with SAM's patch), and I've been losing first/second round matches to people that are ranked really low. And I noticed the stats, they have soo many winners and soo many net play and net winners. I lost first/second round Indian wells, Rome, Madrid, Cincinnati, and the last one, Beijing. (I did well in Grand Slams, maybe because I'm a slow starter, and matches often go 4 to 5 sets).
But here is example of my lost Beijing second round match.
 Tommy Haas def.  Myself with score 6-7, 6-1, 6-2
My winners/UE: 38/ 36
Tommy Haas' winners/UE: 58/27
Tommy Haas' net winners: 32
The reason I bring this up, is that this happens very common. Almost ALL the players that I play, even though they are power baseliners, they suddenly become crazy super net players when they are down 30-0 against me. Then suddenly they reel in 4 consecutive points by coming to the net.
In a 5-set matches in grand slam, some players even have 93 net winners against me. I should've written down the names of the players, but to my knowledge, throughout the play they are usually power baseliner play-style, but become net players when they are losing.
Is this intended? Also, how come soo many winners to UE ? 58 to 27 is too much I believe and not too realistic. Again, I play on professional 10. Thanks for your response, and I just want to clarify.
