Column name "total_output_tokens" contains "total" token strongly indicating real_additive. Statistics show large unbounded magnitude (max 11119), mean far from 1.0 (2506), and 28% zeros - all consistent with an extensive count quantity. No multiplicative signals present (center not near 1.0, no ratio/rate naming). This is a straightforward accumulating count measure. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
