Well, from my experience with the 14" guns, they have strange tendancies. Sometimes, they fire dead on, with basically no spread what so ever. Then the other bit to the time, they go far off in just about every direction imagineable, even at super close range(aka level). I've seen this happen plenty when playing the Russian missions, as often I was able to sometimes get every land to hit, and other times it took almost 3-4 frontal salvos to finish off the 3 destroyers. The 16" guns available on Colorado have a pretty small spread, from what ancidoseable times I've used it, but it's DPM really suffers. The 16" mark 6's on my south dekota seems to have extremely good Y-spread, as it can basically hit any target provided they are flat to you, Aka broadside. It's X spread isn't that bad, but it's noticeable, espially when the target is niether head-on nor broadside, where the rounds will tend to fall on either side of the ship. And the guns aren't good at countering maneuvering due to the X spread, but most guns that are battleship caliber have a hard time anyway.

But to calculate spread, you need to take some base values for a gun firing at a stationary target and the platform the gun is on is stationary, then add velocity in all it's forms(speed, direction, time of shell travel, change in direction, change in speed, etc)
