According to Amit Singhal, Panda was a specific algo change and after that many others took place. So 'Panda 1' and 'Panda 15' were not actually Panda, but different algo changes while keeping Panda on top of everything else.
Some publishers have fixated on our prior Panda algorithm change, but Panda was just one of roughly 500 search improvements we expect to roll out to search this year. In fact, since we launched Panda, we've rolled out over a dozen additional tweaks to our ranking algorithms, and some sites have incorrectly assumed that changes in their rankings were related to Panda.
Also Matt Cutts said that Panda data is not collected daily but when they decide to run that part of the algo.
short version is that it's not data that's updated daily right now. More like when we re-run the algorithms to regen the data.
So it appears it's like a score /grade and it sticks for a while for those already ranked. How often they do it is everyone's guess but we know it can crush your site rankings.
Now we hear stories about people improving their rank here and there, but most so far have been hit in April and in the following updates, not on 2/24.
So the question is: Has anyone hit by the 2/24 algo made a comeback?A serious one I guess, close to pre-Panda traffic levels not the 10% plus or minus.
I'm trying to see if there's a set time penalty or not. If you came back from 2/24, did you by any change contact Google or posted your site in their forums (I refuse to believe that no manual changes are made to it)
Edit: My 4 sites that were not hit by Panda got an 25%-30% boost today, my one Pandalized site kinda down a bit despite many changes.
