I wish there was better public data we could use here to generate these numbers.

But there is a dearth of such numbers that are vaguely current relatively inclusive
and not completely stupid.

So we use the ad placement mechanism as an indirect pointer to user count. Its very rough,
and at best one can say that there are large, medium and small eyeball networks, and
to a first order the algorithm appears to identify networks into these three categories.

I am not trying to tie in address density here - I’m not even sure that would be wise
because, as you well know, NATs hide all kinds of sins and virtues.
