Because any two-window comparison can be an artefact of where the series is cut, the same two columns were recomputed over five different windows: the first nine readings, the middle eight, the last nine, and the two unweighted halves of 13 readings each. Each cell is the unweighted arithmetic mean of that column over the readings in that window. If the published 9 and 9 split were doing the work, the halves split would disagree with it; the point of the table is to let a reader see whether it does.","unit":"mixed","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
