As I understand it, the serve speed number seen on TV and at pro tournaments are taken as the ball leaves the racquet. When you place the 'gun' at the center strap of the net, you have to (1) hit it "up the tee" (e.g., right over the gun) to get an accurate reading, and (2) add 10-15 MPH in order to get equivalent numbers, because it reads the speed as it passes over the net.
