I find it unlikely that user metrics play any role in the Panda. However, Google's vague answers likely make you think this is a possibility and do all you can to improve these metrics just out of fear.
Sure they can do it to Adwords, because it's an even playing field, they have the same data on all the web sites. But not all web sites use WMT, analytics, Adwords, etc.
BTW, I am also seeing one of my sites improve today, it is not a total recovery, but it is an improvement. My other main one is still down. This makes me think that there are also various levels/stages of Panda for more than one factor. But I don't think it is user behavior. I am sure it is all down to content.
