No. I've been told yesterday Federer won almost all his AO titles on a super fast surface, and the grass was quick on all of his Wimbledon wins, and USO's as well.
So he has 2 slams, RG 09/AO 10. Impressive. I believe Rafa has more outside clay, no? But hey, Rafa is the one trick pony here. Federer just has the benefit that 3/4 slams are quick (Ao is debatable, it's still a hardcourt), and just one is slow each year.
You appear to have missed the
at the end of my post.
I really couldn't care less about the diversity of any player's slam wins. A slam is a slam.
