You know the line, "man, if I'd just made a few more putts." I've said it, you've said it, we've all said it walking off 18. Turns out it's probably not true, and there's a stat that proves it.
I get into research from the guy who invented strokes-gained, and where amateur golfers actually lose shots compared to better players. It's not the putting green, and once you hear the split, you might rethink how you spend your practice time entirely.
