The Sensitivity Rating (A comparator for perceived sensitivity) The Sensitivity Rating is a best-effort value used for measuring and comparing the perceived sensitivity. For 2D, the sensitivity rating is called 'Control-Display Gain' (CD Gain). For 3D, the sensitivity rating doesn't really have a term. 'Curvature Focal Length Product' (CFLP) has been suggested to me.   The 360° distance (cm/360°, cm/rev) is not a measurement of sensitivity. It is just the distance to rot
