For a number of years I have kept track of my golf round statistics, fairways in reg "firs", greens in reg "girs", up/down pct and # of putts. These helped me identify my strengths and weaknesses indicating which areas to concentrate on at practice sessions but....... I always felt an ingredient was missing for example some days I would score well despite missing fairways or greens, some days I had 28 putts other days 36 putts. Recently I have added another stat which has really helped me rate my game "My Mental Performance"!
When I believe that I chose the correct shot or putt plus I was fully committed then successfully executed the shot I add a dot next to the fir, gir, putt etc and total the number after the round. This extra stat really opened my eyes to the huge difference in scores my mental discipline makes, when I'm focused all my stats improve when I'm distracted they get worse fast!
So total up your dots each round, be completely honest with yourself and pretty soon you will have an average mental # that you can strive to improve on, it is helping my game and I this hope game management idea will improve those who read this post.
