One of my sites is pretty well back to pre-panda 2.1 in terms of traffic and serps as from 10th Oct.
Traffic was down by about 30%. Serps was down by on average 3-9 places.
What did I do? Very little as I didn't know what was wrong in the first place (no scraped or copied or duplicate content, no weak pages) so just decided to wait with this one. It's also still my best performing site (even postpanda and i didn't want to do anything that might make things worse!)I subscribe to the "guilt by association" theory with this site - that in fact it was more likely others of my sites that Goog didn't like, sites that got more heavily pandalized.
Another site I moved the hosting (part of testing my guilt by association theory) and it recovered two months later and is still ok after a further two months. I subsequently moved another site to different hosting, but after two months that hasn't made any difference.
Sorry - not suggesting any cures for Panda here - just adding my experiences to the overall picture.
