This absorbs cosmetic day-to-day differences such as a feat. credit being added or removed, or punctuation changing, that the loose match in the main dataset would have counted as a change. churn_rate_pct_loose is the figure published in no1-churn-across-8-feeds; churn_rate_pct_strict is the same metric under this stricter match; delta_pp is strict minus loose, in percentage points.","unit":"count","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
