i have no such understanding or information regardign such.
At some point in the early 2000's, the measurement of service speeds changed from being measured at the net to being measured right after contact. That's why such monster servers like Becker, Sampras, Ivanisevic, Filippoussis, and a few more, were regularly clocked below 120 when it is obvious that they were serving much bigger than, for example, the Fed/Nadal/Murray serves being clocked in the 120's and 130's today.
