Ok. We know that a person can have 3 deaths before maint, then 2 more after for an attack. That's 5 per day per person. That's 25 lives. So, if you could do enough damage that you could wipe out 25 of the best ships in the game (normally the IC), then your sector could be considered 'untakable'. Sure, sure, there could be a multi-corporate effort to take out a particular sector or bubble, but in the game I play in that would be unrealistic. (There are really only 3 corporations, we ain't workin together.
So, what would be the minimum level of force required to ensure your sector is untakable? 25*(104,000 * 1.2) damage done in the first 25 shots of a Q-cannon? Is that even possible? That's 3,120,000 damage, for cryin out loud! And the *last* shot is still expected to do 124,800 damage? Zoikes!
