Obviously chances are improved of bringing down an enemy aircraft, the
more guns are being fired, but what is the intricate calculation needed
to prove that?

It seems the guns were aimed to coincide at a range of 250 yards. 250
yards seems awfully distant to me, what they show of the films of the
time, it seems much less than 250 yards, maybe as little as 50 yards,
unless the used telephoto lens?

You know these planes are normally moving pretty fast when they are
shooting at each other?

ISTR the more experienced pilots would have a much closer concentration
point if/when they could - typically 50 yards or less, since it gave
them a devastating hit when they got in really close.
