Column name "percentile" indicates a rank or ordinal position (51-100 range), which is an intensive level measure. Values are bounded [51, 100], centered at ~71, far from both 0 and 1, with no zeros—classic intensive_additive signature. Summing percentile ranks across entities is meaningless; averaging is the natural aggregation. No multiplicative evidence present. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
