Performance rating notation on golf score cards
By fred, Sunday 28 March 2010 à 14:54 :: Golf
In this article, I describe the way I note information about my golf parties. The objective is to gather statistics about the way I play to be able to find where I need to improve my game.
The principle of the rating is to write an entry for each stroke. This allows to analyse if I have troubles with particular golf strokes.
The constraint I used to design the rating notation is to be able to use it on a normal golf card. I also plan to implement it on an electronic mean like a mobile phone or a small tablet but that will be another story.
I use 2 different notations one for the field strokes and one for green strokes.
Field strokes
Field strokes are noted using a few letters. Here is a part of a score card with field strokes (inside the blue line):
The first letter is for the location:
- departure area => D;
- fairway => F;
- rough => R;
- field bunker => C;
- green bunker => B;
- around green => A.
The middle letters are for the club type and kind of stroke. Here are the letters I use for my bag:
- driver => D;
- 3 wood => 3;
- rescue => R;
- 4 to 9;
- pitch => P;
- sandwedge 52° => 52;
- sandwedge 56° => S;
- putter outside the green => Pu.
The optional next letter is for the kind of stroke:
- fade => F;
- draw => D;
- punched => P;
- rolled => R;
- parachute => L.
The last letter is for the result:
- on target => T;
- on the right of the target => D;
- on the left of the target => G;
- short => C;
- long => L.
For the result I use a mix of french and english but you could use what you want while you do not change.
Green strokes
I put a G as the first letter to denote a green stroke. Then the number of steps to the hole and then the result letter as for field stokes.
File
I transfer the notation in files to be able to compute statistics.
Here is the file corresponding to the score card in photo:
