Ok. I knew of those things, like I said. For instance, visitors to my site outside the USA produce a much smaller eCPM than my American visitors who provide a healthy eCPM. I've seen where new links or strong links to a section have boosted the eCPM tremendously, and if the links go stale, the eCPM drops.
I'm familiar with all those things. And I have been familiar with your posts for 5 years, as well as the one time I read your blog years ago. They all have a similar theme.
