Nothing adsense specific like I was expecting. Still a fun tool to play with, though it'd be even more useful to me to see some RPMs over $10. Those are rare, but not unheard of.
Thanks. If you decide to do anything else, my final suggestion would be to adjust the scale on the bottom to something non-linear, or scrollable since those $10+ RPMs are pretty rare in my experience. I would think your average publisher would be most interested in the $1-5 range.
