I googled short game calculator to try and see how good a chipper I am. I found https://www.ritson-sole.com/golf-tips/calculate-a-short-game-handicap/. Basically count all shots within 50 yards of the green divided by the number of holes you had those shots on. The scale is If your handicap is 20 or higher, you should be aiming at a short game handicap of 3.0. Between 19 and 10, you should be about 2.75. Below a 10, you should have 2.5 or better.
Since I found this I have played 5 rounds scoring between 2.44 and 2.76 (14hcp) Does your score match your handicap?
