Especially when for most, the recovery was slow and then the take away of the recovery was instant, like another switch being flipped.
I think what is going on is that once Panda hates you, he hates you forever - if you have been panda stomped, you are forever foresaken to be stomped every time Panda comes around.
BUT this doesn't mean that your site can't steadily increase in rankings due to more people linking, better seo, better content improvements that have always been at play in Google's Algorithms. You are just gaining in SERPS due to the normal algo's. But you are still screwed because Panda doesn't care about 'the rest' of the 500+ algo changes going on at google - Panda comes and stomps you back down.
Once Panda targets a site there is nothing that can be done to overcome it - short of manual google intervention, which google claims doesn't exist.
