"IBU" (International Bitterness Units) is a standard beer intensity measure—an absolute level property of each entity, not an extensive quantity that accumulates. The mean (21.9) and median (16.0) are centered away from both 0 and 1, with a wide range [0, 2600], consistent with an intensive physical property. Summing IBU values across beers is meaningless; averaging is the natural aggregation. High log_symmetry_gain reflects the right-skewed distribution typical of intensity measures, not multiplicative behavior. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
