Column name "from_null_rate" contains "rate" token suggesting multiplicative, but all values are exactly 0.0 (100% zeros, no variance). A rate that is uniformly zero is degenerate - it measures the count/fraction of null occurrences, which is an extensive quantity that accumulates. The naming suggests a proportion/rate, but the data behavior (all zeros, additive accumulation semantics) and table type override the name token. Classified as real_additive with moderate confidence due to name-data conflict. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
