I'm not sure it will be faster at all. Hasn't the WTF been low bouncing medium/slow these last years? But in either case I doubt it will matter much. Fed is as aggressive as Tsonga in this matchup.
I'm not sure if it's actually faster, I think Fed said it was comparatively faster, when compared to last year's big difference between Paris and the WTF. Who knows what the court's though, they have to build it in such a short space of time.
Hopefully a stress-free win for Fed. But I'm not counting on it
