My Finalized was 99.3% of my Estimated for February. I don't think finalized has ever been less than 99% in the years I've been using AdSense.
AdSense is what it is. As I have often said, the price we pay for the ease of implementation, better payouts than most similar programs, relatively reliable payment (used to be reliable payment, but they've been goofing on that in recent months) and low bar to entry is almost complete lack of control. If you want more control, you know what you need to do.
Yup...netmeg nailed it.
