Is it possible that the tanking is the result of the links no longer working and that the new positions are pretty much where they should rank if those links did not exist?
I have to agree with you MB. I think Penguin simply "cleaned out" and devalued lots of web pages, and sites (like mine unfortunately) simply lost some "link juice" and are pretty much ranking where they should be.
I still think that removing some really sour apples, coupled with a greater focus on developing more good, quality links, is the best remedy.
