Talk:61cm Quadruple (Oxygen) Torpedo Mount/@comment-27.33.230.69-20170309161448/@comment-26337865-20170309164448

The expected cost of upgrading quad to quint is 5*1/0.62 = 8.06 devmats and 8.06 screws (using expected value of a geometric distribution) assuming you're using Akashi kai to upgrade, so it's not worth using the slider considering the equipment fodder basically has no value.
