Thanks, good work. It's strange to see Sampras and Goran so low down the list (barely in the top 40).
Speed guns in the 90s didn't clock the speed at the contact point, but several feet closer to the net.
Goran and Sampras would be clocking 140s regularly in Getronics guns. Heck, Goran, even 150?
But in the exo against Courier, Sampras clocked a 136 mph serve. Even in his mid-late 30s. I'm sure he could serve 140s easily in his prime. Becker as well, his fastest clocked serve was 135. Ditto with Krajicek.
