Driving. Approach. Short game. Putting.
Use Smart or Full Tracking to see strokes gained across driving, approach, short game, and putting. Explore recurring misses by club, distance, and situation, then use those priorities to guide practice. Quick Round offers scorecard stats and practice suggestions without shot-level strokes-gained analysis.
How strokes gained works
For a normal shot: expected strokes before the shot − expected strokes after the shot − 1. MTRC uses the distance and lie at each end of the shot, compared with your selected goal: Tour Pro, Scratch, Break 80, Break 90, or Break 100. A positive number means you gained strokes against that benchmark. A negative number means you lost strokes.
