Column name "from_null_rate" contains "rate" token, but this refers to a proportion/percentage (null rate = fraction of nulls), not a multiplicative ratio that compounds. All values are exactly 0.0, indicating this dimension has no null values in the source column being measured. A null rate is an intensive property (a proportion between 0 and 1) where summing across entities is meaningless - only averaging makes sense. Classified as intensive_additive despite "rate" naming because it measures a level/intensity, not a sequential multiplicative factor. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
