Actually our accountancy website SERPs got better after Panda. Penguin they seem to have stayed the same.
Results cache date regularity seem very inconsistent - especially for title and rich snippet updates.
PageRank across the site is between 3 and 4, which usually results in daily or at least weekly cache refreshes. Currently I am only seeing updates every couple of weeks (weekly for the home page which use to be daily). GWT reports indexing 100% of the pages within 1-2 days of submitting a new sitemap though. And the crawl stats graphs are on the up and up every week/month.
I put rich snippet author code onto all of our blog articles too several weeks ago and despite having newish cache dates only about 1 in 10 show the author picture.
I have heard when google slows down that a big update is about to happen. Perhaps it's the google local plus migration slowing down the google servers?
