$56eCPM and $0.05 earnings from 1 impression and 0 clicks? That's what my adsense panel is showing me a few minutes after counter reset.
When did Google Adsense start equalling "GAS"? Wouldn't "GAD" make more sense? BTW this kind of stuff (crazy eCPM) happens when you get small numbers of impressions and someone clicks on it.
Sometimes you have strange numbers, what you have to do is wait until a full day has passed, then the figures for yesterday are most always definitive and correct. GAS makes sense to me because often I see AdSense written this way. So Google AdSense.
