Each point scores a sample of the records registered in that year, as those records are today — so a strong early year can mean good metadata then or re-curation since (compare with Re-Curation Watch). Thin years (fewer than 10 records) — hollow points in Lines, dimmed cells in Grid — have noisy percentages. Results appear as each year finishes; switch View to a radar-plot Grid to watch each use case’s concept profile change year to year. Short ranges sample finer: set From = To for a monthly view of one year, a span of up to four years for a quarterly view. Sampling by Updated instead groups records by when their metadata last changed — the view to watch when re-curating records registered years ago.
