One thing to think about:
daniweb.com was sort of the "poster child" of Panda victimization, so starting in late Februrary, I am sure that lots of sites started mentioning (and linking to) daniweb.com, since they were using it as an example of what happens to a website hit by Panda.
So there is the possibility that much of the notoriety that was generated since late February played a part in the recovery.
Just a thought...
