Eight dates were chosen on each side because that is the largest block available at the September end without overlapping the middle of the series. This is the endpoint-robustness check on the headline: if the headline held only because 13 August or 28 September happened to be unusual days, the period means would not move in the same direction. Means are rounded to the nearest whole stream; change_pct is computed on the unrounded means.","unit":"streams","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
