The column name "year4_avg" explicitly signals an average/level, not a ratio. Center-of-mass (mean=3.10, median=3.09, range 1.27-4.46) is far from both 0.0 and 1.0, indicating an absolute level rather than a ratio. No zeros, strictly positive, bounded range, and the "_avg" suffix all point to intensive_additive: this is a pre-computed average that should be averaged again when aggregating, not summed. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
