I just signed up this week, so this is probably a silly newbie question, but I have been checking my Quick Stats and each day the numbers went down, or a little up and then down again - which I would expect if it was a daily report, not a monthly report? If it was monthly, I would expect the numbers to accumulate, not drop.

This is what I have been seeing:
first day - 258 impressions
2nd day - 169 impressions
3rd day - 178 impressions
4th day - 173 impressions
5th day - 180 impressions
6th day - 175 impressions

So do I have something wrong in my settings? Is this really a daily report even though it says monthly?
