FoC | Slow-Motion Yaw Group Fits
Per-(build, torque) damped-sinusoid fit parameters for the early-flight yaw signal: amplitude A, decay length λ, period, phase φ, offset c, residual RMSE, and a convergence flag. The fit equation is y(d) = A·exp(-d/λ)·sin(2π·d/period + φ) + c, with d measured in feet from the bow.
