Zivush - I think you are right. The testing of panda flux had been in the index for a while. I think that explains why some of the people are seeing gradual ranking losses instead of one major hits.
It feels like Panda has been a weekly minor updates and tweaks. Or a judgement call instantly levied as soon as enough pages are crawled and "site score" analyzed.
