{"id":9474,"slug":"spotify-reported-daily-denominator-check-oct-nov-2026","title":"Independent check on the reported-daily-streams denominator: the Daily column against the first difference of the all-time totals, 12 African artists","source":"kworb.net Spotify all-time artist totals, captured by this desk on 20 dates","source_url":"https:\/\/kworb.net\/spotify\/artists.html","source_type":"computed","method":"The denominator used in spotify-chart-capture-by-artist-oct-nov-2026 is the Daily column of Spotify's all-time artist table. That column is not defined on the source page, so it was checked against a quantity the same table reports independently: the artist's cumulative all-time stream total. For each of the 14 pairs of consecutive calendar days this desk captured (8-9, 9-10, 10-11 and 11-12 October, 16-17, 17-18 and 18-19 October, 22-23, 23-24, 24-25, 25-26 and 26-27 October, 29-30 October and 2-3 November 2026), the second day's all-time total minus the first day's gives an implied one-day volume. first_difference_sum is the sum of those implied volumes; reported_daily_sum is the sum of the Daily column on the same second days. ratio_pct is the first as a percentage of the second: 100 would be exact agreement. negative_differences counts observations where the cumulative all-time total fell between two consecutive days, which is impossible for a cumulative count and is a defect in the source, consistent with the source page's own warning that the section is under construction.","unit":"","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
