Further explanation: Say that ingame each round from a Hispano is equivalent to 3 .50s in lethality. It is actually slightly more, but we'll go with 3 for simplicity. But, to do damage in game, those rounds really need to land on the same part of the aircraft. The single round from the Hispano by definition hits one place, being one round and all

. Due to issues of convergence, dispersion, aim, etc, the 3 .50 caliber rounds it takes to do the same damage may end up on different parts of the plane. Thus in actual virtual combat, 2 Hispanos end up being much more likely to get a one burst kill than the six or so fifties that put out the same theoretical amount of total damage.
