Vertical Jump Calculator
Computes vertical jump height either from flight time (h = g·t²/8, the jump-mat method) or from the difference between jump reach and standing reach, then estimates peak leg power with the Sayers equation and rates the jump against adult benchmarks.

Notes
- Flight-time methods overestimate if you land with bent legs or tucked feet — that lengthens the flight without raising your center of mass.
- The Sayers equation estimates peak power from jump height and body mass within about ±10%.
- Educational estimate for sport and training purposes, not professional coaching or medical advice.
