📋 Legend
Zero Stroke () — Your calibrated minimum-speed stroke. The shaded band in each slope column marks the putt distance where exactly this stroke length is required.
Mid Stroke () — 1.5× your zero stroke — a midpoint reference between minimum and double stroke.
Double Stroke () — Twice your zero stroke length. A useful upper-range benchmark for controlled stroke-length putting before needing to change approach.
Max Stroke exceeded (above ) — The required backswing exceeds your maximum stroke length. For these distances, prioritize increasing clubhead velocity and acceleration through swing tempo rather than extending stroke length further. A longer, slower stroke becomes inconsistent — a shorter, more accelerating motion delivers better speed control.
