There's a lot about this math that is iffy. For example I notice there's an estimation for 1992 on the NES's household penetration, but no relatively solid numbers until 14 years later. The size of the average household has declined over that period of time despite a rise in the number of citizens. Is this accounted for? How do we know how to account for this, precisely?
You use 3 as the average number of people per household but that's one thing I don't see evidence for. It is, however, currently 2.59 now so do you have anything to back you math up? Or are you making half of these numbers up? You're making up the household numbers, what else are you BSing?
I'm sorry, it's really too much work on my part to figure out where you're just trying to justify whatever position you want us to think it right. I know you're pulling numbers out of your ass, though, and you damn well better believe you deserve to be called on it.
You do not have the right to never be offended.
