I was very excited to see the integration of Analytics and Adsense. However, I've been noticing more and more discrepancies between what they report.

I am using one of my sites as a reference and on that site, pretty much every page has cookies from both programs. So they should report identical numbers for impressions and click values, no?

The amounts showing up in Analytics and AdSense are sometimes different! I think, normally it's Analytics that "loses" clicks. I also see .01 difference in click values fairly often - perhaps the rounding off algorithm is different?

Has anybody come across this?
