Interesting, so score wise the Cookie in center of town would reward the most damage hits %.
Yes.
That's why, in my opinion, bomber scoring is the one most removed from any in game 'skill' or 'mission success / efficiency'. Especially when you take into account that larger bombs give you
way more score points per object destroyed as well.
So someone porking bases or killing factories with utmost precision and efficiency will in effect 'hurt' his bomber score a lot, compared to someone juts smashing town centers with bombs as big as possible.
This holds true for the bombing part of attack score, too.
