The X-Factor is the angular separation between your shoulder turn and hip turn at the top of the backswing. If your shoulders rotate 90 degrees and your hips rotate 45 degrees, your X-Factor is 45 degrees. A larger X-Factor means more stored torque in the trunk muscles — and more potential energy to release on the downswing. Research consistently links X-Factor to clubhead speed. Elite tour players average X-Factors of 45-55 degrees. GOATY measures your coil depth and hip-shoulder differential.
