Correct as far as Berdych, Tsonga, Del Potro, Raonic etc. is concerned. For beating Djokovic and Murray, a faster court will help. By this logic, it's easier for him to reach the AO SF than the USO SF, but more difficult to proceed from there.
Well, if we need to be fully honest - for Sf and final it takes JesusFed back, or it's a no go no matter the speed or bounce.
Except for a certain draw at AO ofc
But i'm positive that JesusFed is still there to show up at times, so we'll see.
