Hole-by-hole statistics

1. Number of full swing shots.

2. Number of short shots (anything off the green with less than a full swing).

3. Number of putts.

4. Length of first putt.

Include penalty shots in the count of where they occurred, number 1 or 2.

What the numbers show

These numbers are good:
Par 3s: 102 or 111
Par 4s: 202 or 211
Par 5s: 302, 311, or 212. 202 is nice, too.

These aren’t:
Par 3s: 213
Par 4s: 322
Par 5s: 412

When number 2 is 0, that represents a GIR. Fairway hit? Draw a circle around the number 1 score.

Looked at hole-by-hole, you can see how you got your score, and which part of your game was not ideal:
Number 1 was greater than par minus two.
Number 2 was two or more.
Number 2 plus number 3 was greater than three.
Number 4 and number 3 together are an assessment of your approach putting.

Over a number of rounds

If number 1 is consistently too high, you need swing lessons.

If you have too many twos in number 2, or number 2 plus number 3 is consistently three or more, get some short game lessons.

Too many threes in number 3? Total putts over 34? Putting lessons.

Prioritize improvement in this order: swing, putting, short game.
