Almost all of the researchable hull mods follow a nice orderly stat progression with the exception of Core Neutronium Armor. Neutronium Armor follows the progression at 615 hull, but Core Neutronium is at a very odd 644. Deep Core Neutronium goes back to the nice orderly stat progression by being at 695. I found this very odd. I realize this is really a very tiny issue but something my detail oriented brain noticed. Just thought I would bring it up.
