Great answers, thanks.
Doesn't this beg the question about comparing guys of today with those of old? I mean if Fed for example plays much better on fast surfaces, wouldn't that indicate a "Decline" rather than age. Likewise wouldn't Nadal suffer if he played back when courts were faster in general?
Would Sampras not do as well today due to the slower surface?
Seems like it's a big problem. I read a ton on this subject last night, they slow down the surfaces so fans get more play time and points aren't finished off as quick, but this seems like it would hurt the Feds of the world.
