Gains are observed snapshot differences, not Studio daily totals. Today and Yesterday use your device timezone. Intervals crossing a boundary are excluded. Missing observations are not zero.

Performance compares the same channel and format at similar ages (±25%, minimum one-hour tolerance), with at least five other videos. Approximate dates are excluded. Title patterns are associations, not causes. Story tags are keyword-based; coverage gaps need confirmation.

Collection is scheduled every three hours; runs can be delayed. Page checks happen every five minutes. Refresh does not start collection. Thumbnail history detects URL changes, not pixel changes.
