i've no idea, i constantly remove duplicate content, but i haven't done any big changes which could be the cause. One thing i do know is that, when i was first hit by PANDA, my "not selected" pages hit the sky. I was hoping it can be the opposite now: maybe PANDA is leaving. But as i see others experienced the same, so it might just be some changes on google's side.
