Todd, I agree it shouldn't matter who it is, but unfortunately, the the top players are bigger than the tour. it would be horrible press if the PGA Tour fined a top player and cost them a win. but if those guys would get on board and say that's what they want, it could happen.
Ted, you're right, penalty strokes are the only thing that will get their attention. and they need to get on top of things and get a process in place. the timing issue for each shot i don't think will work. they need to consider other influences as well. a ball with a perfect lie from a good distance should be quicker than ball in a divot on the short side of the green with water in between. if they can figure out how to differentiate those two situations, they will be on to something.
