When I say no correlation, I mean between the page views in adsense (with 100% coverage) and the page views in my own stats. I don't try to record clicks myself.
Maybe everyone has decided to start blocking ads?
My end-of-month adjustments were always very small, but my intra-day 'corrections' seem enormous by comparison this month.
