I use Adsense on a few side projects. I make almost no money on it, but love learning about how it works. However I can't figure out how to use the Adsense reports. I set timeframe all time, and the totals come out to $13.80 (lots of money I know :)But my balance is listed by Google as $86.17. Where did the extra 72.37 come from? How can I find that on the reports?
