It would be better to use data sources that actually have raw data, or it's difficult to tell if you're being BSed by a source/if the research methodology that led to a conclusion is correct or wrong.

Suffice to say that there are quite a few severe problems with this chart. Yamato is ideal with 41cm guns for instance. And Nagato gets fit bonuses from 41cms, which for some odd reason is listed as overweight in this post. And 41cm is never overweight on Fusou - they're merely null-effect on kai form, while fit-bonus on kai ni and non-kai forms.
