Also, hitting the back fence... wouldn't the spin have just as much to do with it as the speed?
It all contributes, as does the roughness of the court.
If you have a really rough slow hard court like the ones Drak is talking about at the Sony Ericsson, then the spin takes to it, and you get really nasty high bounces on your kick serves, and it actually slows down your flatter serves and makes them sit up a bit more.
I didn't get a chance to play on them, but I can't remember ever seeing slower courts. If I had to play on them every day, I can't imagine a pair of sneakers lasting more than 2 weeks.
