How is abnormality measured?

Maximum absolute z-score of observations in the last 7 days, against the preceding 30 observations within a 120-day window. At least 10 baseline observations and nonzero variance are required. A higher score means a larger departure from the recent baseline; it is not a forecast. Missing or restricted history stays unranked. Dates are UTC.
