More interesting tests regarding 51cm.

Seems like ship level affects the overweight penalty and fit bonuses heavily as well; a married ship gets bonuses as compared to a non-married one getting penalties, even though they're using the same loadouts (using the 4* 46cm loadout on Yamato as a comparison). There's the increased luck from marriage but I don't think it affects it by that much.
