I understand that it means that the bullets have a spread, so not all of them will hit their intended target. I've seen tables which list a value for the "spread", but I don't know what exactly that value means in mathematical terms.
Is there a way to determine how many bullets will hit? How does that depend on the distance from the Gatling tower?
Finally, if a bullet misses its target, will it still potentially hit other targets? Is it simply a "hit or no hit" or is it more of, "the bullet will follow this trajectory, now let's see if it will hit anything"?
I've been modeling damage from various towers in different maze configurations, so these kinds of specifics are fairly important for that.
