Averaged over 4 IR skin markers
Correlation model between external IR skin
markers and internal target (marker) motion:
= X,Y,Z motion of target (marker)
= Vertical motion IR skin markers
= 1st derivative of x (speed)

Prediction
a,b,c,d,e fit, calculated to match predicted
with detected target position.
