I was hit by Panda in April 2011 - did tons of improvements, no recovery at all, then hit again by Panda 20 in September 2012.
If whatson is right about this:
I believe the Panda algorithm is determined from:
-average time on site
all relative to the other SERPs or search terms.
Then my site should have recovered.
On a side note - my site ranked very well for 10+ years for it's niche before being hit by Panda.
