There have been some rumors going around that core algo = real time
webmuppet... here's an update on the TheSEMPost story. To put this in context, the comment was made about the relationship between the core algo and Panda, and had some bearing on how people were interpreting the update.
The confusion gets complicated enough that IMO it's not worth sorting out precisely who misunderstood whom and when... there were a lot of people cross-communicating on Twitter, and lots else happening at the same time over the past several days of serps churn. I hope, though, that this is the clarification you need... Google Panda is a Core Ranking Signal, Itís Not Real Time January 13, 2016 by Jennifer Slegg

In my Google Panda Algo article, one of the statements given to me by Google was that Panda was now a core ranking signal. But there was some confusion because people assumed this meant that Panda was now real time. But Google confirmed that this is NOT true. Panda is not real-time
Google, I gather, is still working toward a real time Panda, but it's not there yet.
As I interpret and reconcile what was being said by various bloggers who were commenting on this... while Panda is in the core algorithm, the Panda component of the algorithm still isn't automatically updating, and the recent serps changes that we've been seeing (which Google confirmed were in fact core algorithm updates), therefore did not include any Panda or Penguin updates, though the non-Panda updates may have affected some Panda sites.
Hope that makes sense... I can more or less follow the logic.
