What inputs does the 100m predictor need?

Use a block 30m split, a flying 10m split, wind, and reaction time. The block and fly inputs matter most.

Should I use hand-timed splits?

Use fully automatic, timing-gate, or video-derived splits when possible. Hand times usually need adjustment and can make the prediction too optimistic.

The model is fit on elite and sub-elite men's 100m results and is strongest from roughly 9.6s to 11.1s. Outside that range treat the prediction as a rough guide, not a target.
