The column name "away_xg" refers to expected goals (xG), a cumulative metric in soccer/football that represents the sum of goal-scoring probabilities. Despite median near 1.0 and positive log_symmetry_gain, the presence of zeros (8 basis points), unbounded upper range (max 5.7), and the semantic meaning of xG as an accumulated probability sum all point to real_additive. The "xg" token is not a ratio/rate indicator; it's a summed extensive quantity. High confidence in additive classification. </reasoning> <table_type_conflict>false</table_type_conflict> </result>
