Size history

How it works

• Every day from about 04:00 UTC, Grovs estimates the people and devices in each active segment. The run is spread out over time.
• Each estimate is one point for that date, tagged with the definition it used.
• Archived segments are not measured.
• If a segment is too heavy to estimate, or the estimate fails, that day has no point.
• A point is marked incomplete when part of a window was outside your data retention that day.

Where you see it

• Segment page: Overview charts people and devices over time. A new segment shows "Not enough history yet."
• Segments list: People and Devices show the latest point if it is at most 7 days old and matches the current definition. Otherwise the list shows "Size not computed yet". Open the segment for an exact count.

Editing resets the line

Changing a segment's definition starts a new history line. Points for the old definition stay stored but are no longer shown. Renaming a segment or changing its description does not reset it.
