The data agrees: the column has zeros, a mean of about 36 and a range of 0-112, none of it near 1.0, and the log-symmetry gain is negative. The name and the "min" suffix indicate minutes, a duration, which is an extensive quantity that accumulates when entities are merged, so I classified it as real_additive. The main uncertainty is that it may be a per-person typical daily level, which would be intensive, so confidence is moderate rather than high. </reasoning> <table_type_conflict>false</table_type_conflict> </result>
