Myths Debunked

Your launch monitor data deserves
real physics, not golf myths.

FlushLab is a free, browser-based analysis tool that takes raw launch monitor data and runs it through actual impact mechanics — coefficient of restitution, D-plane ball flight laws, spin loft calculations, and tour-calibrated optimization matrices. Upload a session from any major launch monitor brand and get insights that go way beyond "swing harder."

1.465
Max Driver SF

The real cap isn't 1.50

With a conforming driver (COR 0.83, ~200g head, ~10° loft), the physics cap on smash factor is approximately 1.465 — not the mythical 1.50. Even at an extreme 5° loft you only reach ~1.48. Shorter clubs cap much lower: a pitching wedge tops out around 1.06. When a launch monitor reads above 1.50, that's measurement error — not a superhuman strike. FlushLab calculates the real limit for every club in your bag.

Golf instruction is full of myths.

Common Myth
"The best ball strikers on tour can exceed a 1.50 smash factor."
FlushLab Physics
With conforming equipment, the physics won't let you reach 1.50. The maximum smash factor is derived from COR (capped at 0.83 by the rules), head mass, and loft angle. At a standard 10° driver loft and 200g head, the ceiling is ~1.465. Readings above that are measurement error or non-conforming equipment — not purer strikes.
Common Myth
"Swing path determines where the ball starts."
FlushLab Physics
Face angle accounts for ~80–85% of the ball's starting direction. Club path influences curve, not initial aim. FlushLab's D-plane engine shows you exactly what's happening at impact — so you fix the right variable.
Common Myth
"A smash factor of 1.50 is the goal for every club."
FlushLab Physics
Smash factor drops dramatically as loft increases and COR decreases. A 5-iron maxes out around 1.35. An 8-iron caps near 1.21. A pitching wedge? About 1.06. Chasing "1.50" with your irons is chasing a number that physics doesn't allow. FlushLab shows you the real ceiling for each club.
