How would they be able to tell? Well, maybe their traffic, impressions, etc. are very stable and they see a recurring pattern of changes in EPC every Tuesday.

But I think it is clear that it's updated pretty frequently, though not, say, hourly. And when it updates, it doesn't necessarily cause changes to everyone's EPC, so you may not notice an update.

I tend to focus on bringing up the CTR on low-performing channels (relative to my site's average), and if I can't, changing to different ads. I can't do anything about smart pricing, but I can work on CTR.
