Analytics

Ten rounds tell you where you stand. A few hundred tell you how your game actually behaves. Here are the golf data lessons that only long-term tracking can teach.

New driver, new wedges, new hybrid. Here is how to track golf equipment changes in golfity so you can see, in strokes gained, whether the new club actually helped.

Your launch monitor says your 7-iron carries 155 with tight dispersion. Your round says you missed the green short four times. Both are telling the truth, and here is how to use each one.

Five strokes in one season, broken down shot by shot. The interesting part is not that the scoring average fell. It is that almost none of it came from the two things this golfer was sure were the problem.
