K, I'ma put this together before I hit the cinema in literally 5 min. You can save your thanks for later. Just keep in mind that the following lists are far from complete (esp Fed's - I've got close to 80-90 of his matches by now) and I will most likely keep updating this post going forward as I add more names and #s.

@NonP :
Pete's URS is comparable to Roddick in part because he SnVed far more. (Same applies for Goran, Krajicek, but I think to a lesser extent )
that tends to raise the % of unreturned serves. We saw that Federer's highest unreturned serve%s were mainly when he was SnVing (2001,2003)
Otherwise, I think Sampras' would be clearly below Roddick's, if he was staying back and returners could just get the ball back in
That's only part of the whole picture. Will try to follow up later tonight.
