Only 40%? I don't know. Rias (Balor of Darkness) is above Maou class so naturally she would be stronger than Gasper which means she would be doing most of the work while Gasper is assistanting her. Although given the strain the form puts on her body Gasper must have been there. I would say she's probably 60 or 65% of Fenrir.
