EDIT: Sorry for the huge-ness...
(two huge pics)
Those ships have identical AFR and IFR.
The estimated 1yr and 5yr usage is erroneous.
Apparently that calculation doesn't realize that those components are not subject to maintenance failures.
I wonder if the same error shows up for two ships differing only by the number and type of cargo bays.
The max repair numbers are correct...it costs 25 to repair the bay, and 100 to repair the hangar.
Those components can be hit, they just can't fail due to maintenance.
