Match stats

Browsing the match stats available on the ATP Tennis site was illuminating. Like Andre Agassi at his peak, Federer's stats show why he is dominating. He's in the top ten in the world in a majority of service game stats (service games won, aces, first serve points won, second serve points won, break points saved), while at the SAME TIME being in the top ten in a couple of return of service stats (return games won, points won returning first serve). Which brings up a question for all you observers and practitioners of the game out there:
Where in your experience does the average club player fall with regard to key stats like % serve games won and % return games won? As a reference, Federer's stats are 91% serve games won and 32% return games won (pretty stunning, if you think about it -- but then, he's won 7 of the 12 tournaments he's entered this year!). So, would an NTRP 4.0 or 4.5 player manage, say 70% serve games won, and maybe 20% return games won? Any thoughts?

Well the serve games would be less, probably like %70 or so, ya. And return games %20 actually sounds reasonable. I don't know so much though, I watch 4.0 mens matches and play 4.0 sometimes, but never 4.5...
