You’ll read statistics about golfers on the Professional Tours. A favorite is “greens in regulation”. 
That’s a nice and easy statistic to keep during your round (remember to build your strokes in where relevant) 
but I think there’s a more meaningful stat for most of our golfers to keep on their game if they’re looking to improve. 
            Approach shot performance
For most golfers in the 8 – 20 handicap
 range their ability to hit the green from
 130 – 160 yards with approach shots will 
tell us a lot about their game.
Keep track of that performance in your 
game (if you’re in that category of golfer).
Improvement here will almost always
 have a really big impact on the scorecard.
It also feels great to hit a mid iron high 
and watch it stop and bite on the green.
            If your percentages of greens hit from the 130 – 160 yard range is low, then (and even if your short-game is saving you) come and 
have a swing assessment. This might be down to the wrong lie angle or shaft length, but it often comes down to one of poor setup;
 poor aim; out-to-in swing path; or simply a poor swing plane. Don’t rely on your short-game, gain the pleasure of sweetly struck, 
and accurate approach shots.
