For the other readers, “SG” means strokes gained and it describes where a player is gaining or losing strokes against a given benchmark.
There are apps where you can compare your performance to various standards, tour pro/scratch/5 cap/10 cap etc. I have generally used 15 cap as that was my target but now that I’m passed that, may move to 10.
The basic idea is that, say as a 15 cap standing on the tee of a 370 yard hole that my expected score is 5.1. I hit a drive 230 down the middle. Now that I’m in the fairway 140 out, my expected score is 4.6. I “gained” 0.5 strokes with that drive.
The book “Every Shot Counts” by Mark Broadie describes it in full detail. But you don’t need to specifically grasp the science, the apps will show you the data. The two I use are Arccos and Shot Pattern. No need for two but I’m a data nerd and each does something I like that the other doesn’t so [emoji2373]. Here are some screenshots of the type of thing you can get, some pics from Arccos of my last 20 rounds, and a summary pic from Shot Pattern of a recent round and a sample pic on SP where it lists the SG for each shot (Arccos doesn’t do single shot).
