Does Smart Pricing have certain dates where it changes?

Does anyone see a pattern here?

Like a lot of people posting here, I occasionally see big changes in my EPC, often from one day to the next.

I have been wondering if anyone has been able to detect a pattern, like the first day of the month, every Friday, etc. when the new Smart Pricing payouts go into effect. Two weeks ago I saw my EPC drop to about 15% of the norm, and then two days ago it went back up, both times over night. I can only speculate that this is the result of Smart Pricing, as my impressions and clicks remain pretty much constant. My web sites are about as varied as can be so I can't really imagine it could be the result of advertisers starting and stopping their ad compaigns triggering sudden market changes.

Does anyone have any theories as to when or how often Smart pricing is updated?

The weekends to start with, for terms common to the Monday thru Friday business sector - the payout is reduced.
