GPA is a bounded (1.9-4.0), strictly positive absolute level centered at about 3.4, far from both 0 and 1, and it has no ratio-style naming or units. It is an intensive score on a fixed scale: summing GPAs across entities is meaningless, and averaging is the natural rollup. This makes it intensive_additive.</reasoning> <table_type_conflict>false</table_type_conflict> </result>
