I think those are good numbers on average and using an average is the best we'll be able to do in sh4.

If you look at individual subs within a class (assuming navsource is accurate), some subs had very different fuel capacities. Some gatos had 115,000, some balaos had 94,000. We don't know what kind of upgrades a sub may have gotten throughout the war to improve fuel capacity, if the later built boats within a class had some of those upgrades built in straight from the yard, or why sometimes a later boat in a class has a smaller fuel capacity.
