tournament, was everyone who served and touched the line "too soon"
uniformly called for it?
Suggestion. Continue the use of the magnetic field in tennis to
automate the process. Require certain grade metal in the soles of
shoes and in the heads of racquets (or the strings). Combined with the
metal powder present in tennis ball rubber, a device can be created to
determine that the head of the racquet is in probable contact with the
ball before either shoe is in contact with the line. Over the line OK.
In contact with the line a no-no before the strike -- an alert sounds
giving the umpire the opportunity to make the call. The service motion
happens too fast to trust humans to make the evaluation. Machines are
better. The game improves as we take emotions out of it.
