Hello! In the company I work for, we have been using revive (and openx before) for a while, and until now we used it in a very simple way, just selling ads over time (week, month) for a certain price, nothing complicated. But we want to start selling with CPM, so we need proper statistics, and I realized they are kind of wrong. If on a day we get 65k pageviews (from piwik, something similar from Google analytics as well), I should get arounf the same with revive ads. But for 1 banner displayed 100% of the time, I get 87k impressions, how is this possible? And even for 2 banners, 100% display, they don't have the same amount of impressions (not a big difference, but few thousands). Can someone explain this? Thx
