TrackMan founder Frederik Tuxen teams up with legendary instructor Brian Manzella to unveil two brand-new TrackMan parameters: Smash Index and Spin Index — designed to finally answer the question: did you actually make solid contact?
Key concepts:
• Smash Index: your actual smash factor divided by the maximum possible smash factor for your delivery — normalized for spin loft so you can compare across clubs and conditions
• Spin Index: your actual spin rate relative to expected spin rate for your delivery — reveals gear effect, grooves, and contact quality
• Why a 1.30 smash factor alone can't tell you if it was a good hit
• How low-face driver hits produce 200%+ spin index due to gear effect
• Brian's 10-day field test: real-world applications for fitting and coaching
• Huge implications for club fitting — seeing spin/smash quality independent of delivery
