Thx fo the comment. I think Naka's CI chance increased mainly because she became the flagship. As for KTKM, I suspect high morale has something to do w/ CI, too, but currently I can't find sufficient tests to verify that.

There is a line on the combat page saying "diminishing return or hard-cap" on luck over 50 for torpedo CI rate. Not sure on how it really works till fairly large samples were collected.
