Rows sorted by that column, then the totals recomputed with the largest rows dropped one scenario at a time, and again with named rows excluded. sum_change_pct and mean_change_pct are each scenario against the full set. A finding that moves sharply when a single row leaves is a finding about that row.","unit":"artists","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
