Three practical demands shape long-range gunnery: rapid salvo delivery, quick ranging, and sustained weight of fire. Ranging needs several shells because each fall of shot supplies another correction. Incomparable begins with the assumption that the largest calibre is the decisive characteristic. This pushes rate of fire and ranging performance aside before the design has shown that it can use its theoretical reach. Those demands provide the standard for the rest of the comparison.

Calibre versus usable firepower
The design problem is framed around rate of fire, ranging speed, and sustained weight of fire rather than the spectacle of mounting the largest possible gun.
