I know this is an old thread, but I want to add my opinion as well.
I swing normally at about 60% on groundstrokes, up to 70% if I'm hitting cleanly. I don't need to go anymore then that because I simply don't like the margins that come with swinging out on every shot.
That being said, when I do hit for about 90%+ just gunning for a winner, it's pretty big. Especially by comparison of my normal strokes.
My serve on the other hand is all about generating the most RHS possible for the most consistent spin orientated shot I can get.
