Feb 8-10 is too early to be part of the Panda update - that happened around Feb 24.
Would you say it's safe to assume that Panda is continuing to spread such that more sites are being hit even a week or two weeks after Feb 24? I was hit March 11. I can only assume it was Panda, as most of the pages that took the hardest hit in WMT (comparing the day before and the day after penalty), were my "thin" pages. I think Panda is still hitting sites as their deep crawl comes around (I only see a deep crawl about once every 45 days). So I tend to think the algorithm began on Feb 24, but it is still ongoing.
