[QUOTE=schmke;6933033]The flaw in your thinking is that if some players are winning, then some are losing too. So they'd move down and so there isn't a mass move up of ratings. The system more or less stays balanced.
Perhaps what the issue is that 40+ players tend to play more doubles and are relatively better at that, so a 4.0 "singles" player would easily beat one a 4.0 "doubles" player and there is the perception the 40+ doubles guy is overrated.
I dont really care either way, but when you are only playing people in the 40+ league, it's not a true representation of all the players in the game as you are only competing against a select demographic. From what I have seen in my area all the better 40+ players are staying in the 18+ leagues as they want the extra competition. That probably further dilutes the level of tennis needed to win. As I see it people will start playing up a .5 level and will slowly increase their rating.
