Secret of Feedback; Rule # 4: Watch the Trajectory of Each Shot

Watch most golfers hitting wedge shots on the practice range and what you see are people beating balls. They think they're working on their wedge games, but all they're really doing is making a wedge swing, striking the ball, taking a quick glance to see whether or not it's airborne, then looking back at the pile of balls and raking another into place for the next swing. They don't watch how far the ball flies, they don't notice how high it goes, and they sometimes don't even have a target in mind. They have no idea what they, or their shots, are doing. 
Whenever I see a "rake and beater,"  I wait until he's hit a ball in begun looking for the next one to hit, then I say, "look at me, please." Once I have his attention, I ask, without looking back, what did that shot just do? Where did that ball go? Most of the time they can't tell me. They have learned absolutely nothing, so they have wasted the time it took to get ball and body into position and make the swing. This isn't practice, because they aren't learning anything. It's just exercise. 
Not that I'm against exercise. I just prefer exercise with good feedback, which is just as much fun, just as healthy, and has the added benefit that it helps you become a better golfer. So I want you to learn to notice and care about the height and character of each shots trajectory, and make it a habit to watch your shots and flight. If you are making a true finesse swing, with no hand-muscle control and no hitting action, you will create consistent trajectories and a consistent, repeatable amount of backspin on the shots as the land. (To evaluate backspin, you occasionally must hit to a well maintained greens service for feedback on your shots bounce and roll behavior, particularly on shots inside 30 yards.)

These are the questions you should be answering after every shot you hit: did it land the distance you wanted? Or was it too long or too short? Instinctively you already know if it was right or left of the target. Did it have the trajectory you wanted? Did it have the same trajectory as the previous shots you been hitting, and if not, why not? Finally, would it have behaved as desired on the golf course, to a real green with a real pin?
