The column name "Training compute upper bound" indicates an absolute extensive quantity (compute resources), not a ratio. The values are extremely large magnitude (1e+18 to 1e+27), strictly positive with no zeros, and unbounded—classic real_additive characteristics. Center-of-mass is far from 1.0, ruling out ratio_multiplicative. This is a computational resource measure that accumulates when volumes merge. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
