Kind of. From this Wiki's explanation, "summoned creatures only have a third of the strength of a Normal-ranked monster."

So a monster/summon that was originally above Normal rank, like the Raid-rank Garnet Dragon, first gets its abilities/power lowered to that of a Normal-rank monster. THEN its power is further reduced to a third of their stats at Normal rank, putting them at Minion-rank.

(Also, most accurately, it would be 33.3333333...%, but semantics.)
