The name "material_delta" suggests a change or difference quantity, which could be either an absolute delta (additive) or a ratio (multiplicative). However, values are small positive decimals (0.005 to 0.02) centered far from 1.0, ruling out ratio_multiplicative. The "delta" naming typically indicates an absolute change level rather than an extensive quantity that accumulates, pointing to intensive_additive. On a DIMENSION table, this likely represents a characteristic delta/change property of each entity. Confidence reduced due to ambiguity between intensive vs real_additive without more context, and user confirmation requested given the small sample size (n=2). </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
