Golf improvement

Ask a golfer what they hit from 100 yards and you get an instant answer. Ask them to prove it with data, and the picture usually falls apart.

Good course management is not about playing safe. It is about making the highest expected-value decision on every shot — and your own data tells you what that decision is.

One double or triple bogey can sink an otherwise solid round. Here is what the data says blow-up holes really cost you, and where they come from.

One shot to the green sounds simple, but par 3 scoring is consistently worse than golfers expect. The data explains why these holes quietly cost you strokes and how to stop the bleeding.

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.
