The method

How Mully works

Mully is the coach behind every OpenCaddie plan, coaching rather than another dashboard. Here's exactly how a plan gets made, and the named sources each step leans on.

  1. Step 1 · Reads

    Reads everything you've already got

    Mully pulls your launch-monitor shots, your on-course rounds, and your bag with its target carry distances into one picture. It works with the data you already capture, whatever you use to capture it.

    TrackMan, SkyTrak, Foresight, GSPro, Garmin, Arccos

    Worked example

    7-iron: 157 yd carry across 23 shots, dispersion +/- 12 yd, low point behind the ball.

  2. Step 2 · Diagnoses

    Diagnoses the cause, not the symptom

    A fat 7-iron is a symptom. Mully reads the delivery numbers against the ball-flight laws and compares your stats to benchmarks for your handicap, then names the actual cause.

    Worked example

    157 vs your 165 target, low point behind the ball: a fat-contact pattern, not a distance problem.

  3. Step 3 · Prescribes

    Prescribes a drill by name

    Mully picks from a catalog of drills coaches actually prescribe, matches the one that fits your cause, and tunes it to your numbers. A named drill, not an AI summary telling you to 'improve consistency.'

    60-drill catalog

    Worked example

    Towel-behind-the-ball drill, 7-iron, 165 yd target, 3 sets of 10.

  4. Step 4 · Adapts

    Adapts to how it felt

    After the session you tell Mully it clicked, you struggled, or you want to repeat it. The next day's Practice Station adapts based on how today landed. The coaching gets sharper the more you play.

    Adaptive Practice Station

    Worked example

    You log 'clicked.' Your next Practice Station adds a target window and moves on to the 8-iron.

Mully's instruction is grounded only in established authorities, never social-media swing tips. Every benchmark traces to a named source — see the full sourcing tree →
