{"id":10070,"slug":"spotify-alltime-africa-ratio-by-window","title":"How the African accrual ratio behaves at shorter windows, October to November 2026","source":"Spotify all-time artist leaderboard as collected by the Afrobeats Wire data desk on 20 dates, 11 October to 11 November 2026","source_url":"","source_type":"computed","method":"The headline ratio recomputed on every adjacent pair of the desk\u2019s 20 leaderboard captures, and then on the full window end to end for comparison. accrual_to_bank_ratio is the eight African artists\u2019 share of the top 1,000\u2019s streams added in that window divided by their share of the top 1,000\u2019s lifetime bank at the end of it. Captures are not evenly spaced: the gaps between adjacent captures range from one to three days. Negative ratios occur where the upstream lifetime counter restated African catalogues downward within the window, which it does: across the 20 captures the eight carry 10 downward restatements between them, the largest a fall of 33.4 million on a single artist. The table is published to show that the finding is a property of the full window and is not legible at daily resolution, not to suggest that the short windows are independent measurements of the same thing.","unit":"ratio","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
