Fair enough, but I can serve like that
Well of course the average serve speed would be slow in those situations, considering how each player is using there serve... I mean I personally just mindlessly hit the serve as hard as I can to give it as much power as I can, whereas the top players vary it so much... I'm pretty sure if we had a average serve speed of an ATP players when they are hitting it as flat and hard as they can into the box we'll have quite a few 133+mph stats...
