No, you got it wrong as usual.

Vic's analysis (with his colleague) is here. The speed goes from 7 (top of swing) to 25 (lowest point of swing) to 71 near impact (in that analysis, contact was in front of the chest).

Did you really think Federer would swing at 17 mph at impact? I think even casual tennis and golf players know that the number is way too small.
