If the site was hit by Panda, wouldn't you lose ranking on all keywords?
Not necessarily, if your site was so much more elite to the other choices.
For example I kept about 15 #1 rankings after panda, even though my site was devastated by it as a whole. Why? Let's look at the competition for those terms.
My page= 15 yo domain, 23,000 unique domain links (1,000 .edu,.gov), and honestly superior content to all competition plus a lot more of it.
My nearest competition for that term = 2 yo domain, 1,213 unique domain links (0 .edu,.gov). They have maybe 1/10 of the amount of content we have.
So I think Panda is just an overall devaluation, not a penalty (-3,-5) to all pages.
