Measurement Model

Along the swept meridian, r = L(meridianAngle) - (F(meridianAngle) + W).
Negative r: with motion. Positive: against. Near zero: neutral.
The zone widens with small pupil and hazy media.
Off a principal meridian the reflex breaks from the streak.
Simplified model for educational and research purposes -- not a clinical diagnostic tool.
