Column name "support_floor" indicates a threshold or minimum level constraint - an intensive property. All values are constant at 50.0, far from both 0.0 and 1.0, ruling out ratio_multiplicative. The "floor" semantic means this is a level/threshold that should be averaged across entities, not summed. Classified as intensive_additive with sum excluded. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
