so if a bomber takes 2 gunsights at 100m and 1 at 100 m then how many at 150 m?

nope you got the fixed point of view concept right but the moving point of view concept wrong

if you move forward fov should increase to keep at 1:1 aspect ratio but currently it remains constant and some implementation do it even worse and when you close by fov decreases

gates intelligently as usual figured it out:
