Strokes gained

Two golfers can both hit 10 greens in regulation and lose three shots to each other on approach. GIR cannot see that gap. Strokes gained approach can.

Bombing it 290 looks great on the tee box, but does distance actually lower your scores? The strokes gained data on amateur driving is more nuanced than either side of the argument admits.

Breaking 80 is a different problem than breaking 90. The golfer on the bubble is already competent everywhere, so the four strokes hide in two places at once instead of one.

Amateurs treat 100 yards as a green light and then get frustrated when the ball lands 40 feet away. The proximity data says that result is completely normal — here is what to actually expect.

Breaking 90 is not about one heroic round. The strokes gained data shows it comes down to a specific shift in one category, and it is rarely the one golfers practice most.

Strokes gained off the tee sounds technical, but the meaning is simple: it scores your driver and fairway wood tee shots against what a benchmark golfer would do from the same spot.
