AdMob total requests disappearing and total revenue decreasing

Surely I'm not the only one, but I haven't been able to find any explanation on here or with a quick Google search; I apologize in advance if this question has been asked here before.

I keep a daily log of my AdMob stats for开发者_如何学运维 my Android apps on the market, and I've seen a handful of days (sometimes consecutive) where both the Total Requests and the Total Revenue fields are going down. Obviously the eCPM, Fill Rate and RPM will change [and possibly decrease] but how are the totals going down?? I wasn't sure if maybe these are actually projections, but I couldn't find anything stating such in the AdMob help, either. Has anyone else seen this?

oh, I just got what you mean by total revenue going down, weird...

I suppose total revenue is only shown for the period of time selected, if you view a 30 or 90 days window, total revenue going down means the revenue over that period is lower than it was for the previous same-length period.

Check "pending earning"s to see the all-time total amount on your account.

You can alter the date range by clicking "Set table date range" and get the total revenue calculated from the start.
