I am unable to figure out how they came up with the crew numbers as well as the refrigerated bay numbers come from on page 73 & 74 of the TOAUE.

For the non-gunners I get 63, which is what the book states. For gunners, I get 73, the same. but at the end it says that he adds 229 extra crew, stating that would allow him to carry triple its min. of non-gunners and double his min of gunners. That would be 189 and 146 respectfully. but that add up to 335, 106 more than the 229 that was added.

Also, I can’t find anything on bays calculating refrigerated bay size.
