I think the USTA should take a good look at the ELO type rating system that chess, table tennis & a number of other competitive activities use. It seems much more accurate. For those of you that aren't familiar with it. .. basically everyone has a numerical rating. When you play someone else, your rating is weighed against your opponent's and if you win, your rating goes up. . . lose and it goes down. The disparity between you & your opponent's ratings will determine how much your rating will change. The bigger the upset, the bigger the gain for the underdog and the bigger the loss for the favorite. When I played in table tennis leagues years ago, everything was pretty clearcut. Everyone had a much better idea of where they stood.
