The data for the open waist positions is the most relevant to the majority of man-served guns; it was a pintle-type mount rather than one in a reinforced ball socket mount, similar to the majority of the rear gunners in the sim. Scharf ring and pintle mounts are much more subject to vibration and flex.

Note also that the data is for ground testing, which means that there is no relative motion to joggle the gunner's elbow or guesstimations about where the target was going to be when the bullets got there. Chances are good that the guns were sighted in and then clamped down and fired by a fixed remote to get those figures in order to eliminate human error.
