Has it been established that Penguin operates like Panda used to?
(1) There was some speculation based on a video hangout with John Mueller that Penguin refreshed regularly. It does not, it never did, and the truth is, it refreshes very rarely.
Google has told us that Penguin is rarely refreshed, unlike Panda and we didn't miss any Penguin refreshes since.
