Here's something I don't understand. Why do people keep saying that the AO suits Djokovic and Murray more because it's slower, when Djokovic has a higher winning % at the USO, and Murray has multiple cincy titles? I don't know about his winning percentages, but I'd imagine they're very close as well. I know close history suggests that they're better at the AO (3 wins, 2 finals) but I still think they're better on faster hard courts. They just so happen to be better than Federer and Nadal on slower ones.
