Never caught up for me which is bad news on a weekday since I won't pull it back over a weekend.

Is Google suffering a lack of ad inventory at the moment in some sectors?

I ask that since my traffic has been very consistent this week with my logs showing hardly a variation from day to day yet Google Page Impressions are showing a 10-15% difference.
