has anyone seen any recoveries from a Penguin demotion recently - I mean a decent initial fall of a number of pages happening on the 24th April rather than a drop of a few positions?
I'm not sure what you mean by this. A drop of a few positions isn't a trivial matter in most cases. It can cause almost as big a traffic loss as losing a hundred positions.
