I just thought this morning I would post the pic I received from gutted just over a year ago that started me on all this craziness in my specialty of constant bearing longitudinal spread attacks. This really shows why, in this family of attack methods, range cancels out of the equation and simply doesn't matter:
The blue line is your course, the green line represents your shoot bearing. As the target crosses the shoot bearing, no matter what his range, he gets tagged. Neat, huh? This is the diagram that started my slow slide into insanity!:rotfl:
