    The DSMAC AI system computed contrast maps of images, which it then combined in a buffer and then averaged.

    A common method of expressing the amount of constriction is by "points". A "point" is equivalent to 0.025 mm (0.001 in) of constriction of the inner diameter of a choke. Hence, 40 points of constriction would correspond to a constriction of 0.040 inch (≈ 1 mm) in the inner diameter of a choke, corresponding to "Extra Full".
