Remember also that Penguin (just like Panda) is not a real-time algorithm for now - it will refresh only periodically.
How often has the Panda algo been refreshed? Is there any patterns to the times refreshed and so on? Just trying to make some sort of guess when Penguin might get refreshed. I was hoping that it would be today (being the 24th after they ran it on the 24th of last month).
