Column name "query_ms" indicates a duration measurement (milliseconds), which is an intensive physical quantity. Values are strictly positive, centered away from both 0 and 1 (mean=3.52, median=1.19), with no zeros. This is a performance metric representing query execution time per entity - an absolute level where averaging is meaningful but summing across entities is not (you don't add up query times). Classified as intensive_additive with mean as the primary reducer. </reasoning> <table_type_conflict>false</table_type_conflict> </result>
