As my gift to everyone on this momentous occasion I present to you the formula to calculating the ratio difference in effective accuracy between weapons (taking into account scatter angle and scatter ratio!)
((1-x) + L / x*(atgb)^2*3.14*o) / ((1-y) + M / y*(ctgd)^2*3.14*p)
x,y = base chances of weapon to miss
L, M = sizes (square CoH metres) of target
a, c = distances of engagement
b, d = scatter angle
o, p = scatter ratio. Must be 0<o<1 and 0<p<1. If o,p = 1, then no shots ever hit. If o,p = 0, then all shots will always hit the intended original target area.
Enjoy.
