The column name "Best score" indicates an intensive level (a quality metric), not an extensive quantity. Values are bounded [0.0, 1.0] and represent normalized scores, which are intensive measures where summing is meaningless but averaging/max/min are natural. The "best" qualifier and "across scorers" aggregation confirm this is already a max-reduced level at the entity grain. Classified as intensive_additive with max as primary reducer since it represents the best (maximum) score already computed. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
