But that is not at the pro level. Given professionally trained technique on both sides of the court, a 6'2 person *will* serve harder and with more margin of error than a 5'5 person. The height of the net and distance to the service line highly limit the safeties of serving over 115 as a shorter person; someone tall enough to hit the serve down into the court rather up-and-down will not experience the same limiting factor.
