    How is serve speed measured at the pro matches? It seems that the ballistic coefficient of a tennis ball must be pretty miserable (i.e., slows down very quickly), and I wonder if the speed is measured at the racquet face, opposite court, average over distance travelled, etc. Anybody know fer shur?

    Thanks!

    The serve speed you see at tournaments is measured using a radar gun behind the server so the speed indicated is the speed of the ball off the racquet face. It is well known that the ball speed lessens by up to 1/2 by the time it gets to the returner.

    Yeah, it's a radar gun.

    There's a guy behind the chair umpire that has a gun pointing from place to place.

    No, the radar device is mounted on the fence behind the players--there's one on each end of the court.

    So the speed is measured as it crosses the net?
