Was thinking about this earlier. Does the dispersion in this game depend on the turret, or the barrel? For example:
One triple-barreled secondary turret fires at a DD. If one of its shells hit, is there a higher chance to get all 3 shells to hit from that salvo, since the turret essentially aimed all barrels at that same spot?
Basically, is it more likely to miss all shells or hit all shells, when compared to three turrets with 1 barrel each firing at the same DD?
I don't know exactly how things are modelled in the code, but IRL there were both per-turret and per-barrel effects, as well as, while finding the range, deliberate per-barrel dispersion introduced to create a "ladder" of shells to allow determination of how far off-target in range a salvo was falling. Once consistent straddles were being made, the ship would switch to firing salvoes with all shells aimed for the same range.
