The column name "Training chip-hours" indicates a resource consumption measure (compute-time × hardware units), which is an extensive quantity. The wide range (1.0 to 132M), strictly positive values, and large unbounded magnitude all point to real_additive. The unit "chip-hours" is a product of chips and hours, but this represents accumulated resource usage (additive), not a cross-product of incompatible measures (tensorial). High confidence in real_additive classification. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
