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).
By drawing your misses back 34 inches you leave yourself with the kinds of money putts you’ll be facing throughout the round: those all-important 3- to 12-footers. Draining those “must makes” during Drawback will give you some putting mojo to take to the course.
The challenge in hitting this type of wedge shot from a tight lie is to make certain that the bottom of your swing arc is perfectly positioned so that your club kisses the dirt immediately after it makes contact with the ball.
