Daily drop and spike warnings are now computed with the anomaly model of the daily volume: the expected volume for that day of the week, and how far the real volume strayed from it.
Update, September 29: the traffic tab of an event draws the expected volume and the drop and spike levels, so you see why a day raised a warning and why another did not.
Who it is for: anyone who was tired of a Monday warning on a Sunday volume.
Where: the warnings of every event, and its traffic tab. Docs: Warnings and updates.
