They just added some new features like Effective CPM. This might explain the reporting lag we've seen for the past week or so.
Just to echo previous comments, I've happened to check in mid-afternoon a few days recently, and Adsense has shown ZIPPO for the day ... so at least for me, the lag time in reporting seems to have increased ... but not too big of deal, since it "catches" up the next day. In terms of numbers/trends, June is "normal" for me so far ... alek
It is lagging more and more. I'm patient enough to wait but curious as to why. It's taking about one and a half days to show my full results currently although it fluctuates.
Since about Monday, my only about half my page views and clicks that went with them were showing. I just had a bunch of them show up this morning, so my numbers just shot up a little, phew! I thought my stats were looking low compared to the traffic I knew I had had.
