Anomaly Weeks(4.2.3)

How many weeks in the selected period sat outside the portfolio-wide control limits—unusually high, or unusually low, against a baseline drawn from every complete week the workspace has sent events. Movement here often points to a shared external event rather than to independent project issues. Where two standard deviations below the mean falls at or below zero there is no lower limit, and only high weeks can be counted. The limits themselves need more than one complete week of portfolio activity to exist at all: with a single complete week there is no standard deviation, so there is no band for any week to sit outside of. A zero on this card is a real reading—the limits exist, and no week crossed them. Where no week could be judged, or the selected period holds no weeks of activity at all, the card shows a dash instead, because a zero would claim an all-clear that was never measured. The week in progress is not counted: only complete weeks enter this number, so it does not change as the current week fills.
