Martin, my metrics from before Panda hit and immediately after were basically the same overall (just looking at the site averages). No real difference to speak of, so in my case Panda demotions haven't made getting out of Panda more difficult. That's not to say it's not the case for others.
What I can say though, is that despite all the things I've done to improve the quality of my site, my overall metrics have only marginally improved. That suggests to me that we haven't really made much difference to our visitors' perception of the quality of the site.
I believe that the biggest hurdle to getting out of Panda (if you assume user metrics tell you everything you need to know about your site's quality) is knowing where the threshold is. I've recently been able to obtain the stats of another site in my niche that hasn't been hit by Panda and what I've discovered has shocked me. Their exit rate is absolutely miles lower than mine.
18 months of trying should have told me that, but now I have a much better idea of the scale of the task ahead. I've effectively been nibbling at the problem, even though it felt like I was really going for it.
