Google will never tell us the facts behind Panda, that would have every two bit webmaster designing sites for Panda and we'd all be back to where we started.
Face it, forget Google SEO, design your pages the way you want them to be. The way you think will attract visitors to your site. That's how it all started off until some smart alec worked out that keyword stuffing the title worked wonders.
The logic behind Panda may well be more convoluted than any of us can imagine. And, imo, beating Bing has to be a major part it.
