I think a lot of these can be readily confirmed based on pictures. For example, Japanese destroyers all had the same hull number based on the unit assigned. so if they all had 21, then they are of the 21st. Capital ships are also pretty well known as is. Battles participated is also pretty easy as its all over the internet including wikipedia and such. There's also operational logs translated in online archives. I'm not sure how they get the cruiser formations though.
