As crobb305 is observing the rotation of some sites I think this is the reset of "user metrics confirmation". All pandalized sites have this but on a different day and i a more or less heavy way.
I definitely think this is realtime evidence of testing or machine learning. I've watched this rotation for several weeks, and it is predictable. These sites never seem to move above page 3 or 4, but they may eventually. They seem to be cresting a little higher with each iteration.
