Missing greens isn’t all bad. It depends on where you miss them. You can often get back in the hole with your basic pitch or chip. It’s the tough lies to watch out for the ones that test your finesse and precision.
That stat which comes from putting studies I’ve done using PGA Tour ShotLink data should scare you. Say you face 12 putts of 30 or more feet per round (which is about right for a mid-handicapper).
Always escape from trouble on the first try—always! Escape into a better position than you would have been in had your previous shot not found trouble. It’s important to remember that the target for your recovery shot is as important as how well you hit it.
