6. One-Mark Procedure. You get to mark your ball once on every green. If it’s really dirty, go ahead and do that as soon as you get there, but then putt out or leave it alone after the first putt. If the ball’s not dirty, save time, don’t mark it now, because you might want to later. The guys in the fairway accustomed to watching you mark and place three times on every green will get a kick out of this. Plus, you’ll have far fewer instances of the ball moving involuntarily, too.
