About these results

Daily events require a change of at least 50% and 100 units. Steps compare three-day averages and require all three later days to remain at least 30% above or below the baseline.

Blank cells and absent dates stay missing. Period comparisons require complete observations. Duplicate date/series cells are summed. Events identify timing and magnitude; investigate causes against your release history.
