I was also thinking of times when your timing gets off in round. It would be nice to take a couple practice swings to get back in timing. Happened bad to me last night. Had a great front 9. I hit one bad shot, then another, then a couple bad putts adn triple bogey later. The rest of the back 9 didn't get any better. Went from a below par front 9 to a +10 for the round. The practice swing may or may not helped. And admittedly, the wife nagging behind me didn't help either.
