Campaigns' placement performance updated only once daily?

[Anna Nguyen]

I have a script that iterates through our campaigns and ad groups, finds placements that are "underperforming", and "remove" them (calls MutateJobService.mutate adding a NegativeAdGroupCriterion for each placement).  The script runs hourly.  The overwhelming majority of underperforming placements are found during the 10pm run.  It appears that placement performance is updated only once daily sometime between 9pm and 10pm.  Is that correct?
