True. I suppose only when we see Uryu's Vollstandig will we be able to compare the one to the other, only having to account for Uryu's development between uses. Or perhaps if we see Uryu fighting a Stern Ritter and compare the two in their base forms. Of course, this will only serve as proof that Uryu is BA. :D
