Speed Potential Estimator

JavaScript required for interactive calculator.

Heuristic Formula: Longer levers (wingspan) + greater rotational mobility + vertical force = higher potential speed.

Example: A 6'0" golfer with average mobility has a theoretical max driver speed of roughly 110-115 mph if their kinematic sequence is fully optimized.

Are you leaving speed on the table?

Most amateur golfers swing well below their theoretical maximum because their kinematic sequence is flawed. They bleed energy before impact. If this tool suggests your max is 110mph, but you currently swing at 95mph, you do not necessarily need to hit the gym; you need to fix your sequence.
