From 12 to 4: How a persistent over-the-top move was costing Marcus eight shots a round
Marcus arrived with a swing built around compensation. Fifteen years of weekend golf had layered fix upon fix — a strong grip to mask an early release, a wide stance to stabilise a lateral slide, a deliberate pause at the top to prevent casting. Launch monitor data told the real story: 8.4° out-to-in club path, 14° open face at impact, 38-yard average dispersion off the tee.
Diagnostic Findings
- TrackMan session: 8.4° out-to-in path, 3,100 rpm spin average
- K-VEST analysis identified early upper-body rotation (X-factor loss at P5)
- Slow-motion capture: club crossing the line by 22° at P4
"I stopped trying to fix symptoms. James identified the root cause in the first session. The rest was repetition."
