The name "vRk" suggests a rank (likely volume rank). The values are positive integers from 1 to 2252 with a median of 273 and a mean of 397, which is far from 1.0, so a ratio is ruled out. The low distinct fraction suggests repeated rank positions across dates. Ranks are meaningful only ordinally along the sequence, and they are not a raw extensive quantity, so ordinal_additive fits better than real_additive. Confidence is moderate because the name is cryptic and no reconstruction signals were supplied. The log_symmetry_gain is positive, but it is explained by the right-skewed rank distribution and is not enough to indicate a multiplicative measure. </reasoning> <table_type_conflict>false</table_type_conflict> </result>
