Once again, while I like the concept, way too many questions\ variables:
-- Slow play in front of you
-- Lost balls, in the hazard, OB scenarios
-- Waiting for you or your opponent to get a rules decision
-- Weather considerations.
-- Where to put the shot clocks so both players and fan can see them, for every player on every hole.
-- When exactly to start the timer? When they get to their ball? After their opponent hits? When their opponents ball is in the air.
-- What to do if fans are being noisy and taking snaps?
-- etc, etc.
I'm just having a hard time seeing doing these things on the course. I think they just need to enforce what they have with one small tweak. First clock violation, a warning.... every subsequent violation, 1 shot penalty instead of fines which is what I think they do now....if a ref has the ballz to take it that far.
