Wind-Adjust Sprint or Jump Marks
Positive = tailwind

m₀ = m + (c₀·w + c₁·w·m + c₂·w²)

(Moinat et al. 2018 coefficients for 100m: c₀= -0.0449, c₁= 0.009459, c₂= -0.0042 — a tailwind-aided time corrects slower)
Predicted 100m Mark at +0.0 m/s
9.65 s
still-air equivalent of 9.58 s with 2.0 m/s wind
Predicted Mark at +2.0 m/s (max legal tailwind)
9.58 s

Coefficients are statistical averages per event — individual aerodynamics, altitude, and gusting all shift the real effect. Official results always stand as run; use corrections for fair comparisons, not record claims.
