What could go wrong with a six-gun turret?

The rough rule of thumb doubles the damage problem with each added gun, reaching thirty-two times the single-gun baseline for six guns. The numerical estimate comes from a remembered family heuristic.

The estimate treats each additional gun as another doubling of the mounting's damage problem. Its sequence reaches eight for four guns, sixteen for five, and thirty-two for six, relative to a single-gun baseline. Alex Clarke recalls this as his father's rough rule of thumb. The numerical relationship is a remembered heuristic, without a calculation or test establishing it as an engineering law.
