I think some of the delay in recalculating is that Panda works at a very basic level - it's what Google calls the "document classifier". I have a feeling that particular type of routine does not run as often as the rest of the scoring that is built on top of it. My current research - looking through patents, papers, and posts that mention "document classifiers".
