Efficiency (Distance per MPH)

Full Definition

Efficiency measures carry distance divided by club speed, showing how effectively you convert swing speed into distance. It combines the effects of smash factor, launch conditions, and spin optimization. Higher efficiency means you're maximizing distance from your available speed.

Formula

Optimal RangeGeneral guidance based on tour averages. Your optimal range depends on swing speed, physical attributes, and individual technique. Many golfers succeed with metrics outside these ranges.

Why It Matters

Efficiency tells you if you're getting the distance you should from your swing speed. Low efficiency suggests room for improvement through better strike quality, optimized launch, or equipment changes—without swinging harder.
