Ok, I understand that. But, I still don't see a need to break it down into smaller modules just because you cannot/will not use that level. At that point it becomes nothing more than profit (or as a 'last-man' defense that kills all - and the ship still won't jump - leaving it open for actual boarding and removal of modules or taken as a prize --- not now maybe, but who knows the future). But all it is good for is profit.
The ship will still jump after so much damage. There is a limit to how useful they are. It does seem like a bit of waste to have that extra percentage. But hell it's a better find then what I find anymore.
