Hmm.. My only problem with that is: Where was that Physical Augmentation when Ruby slugged that White Fang member in Volume 2: Mountain Glenn with right hook and everything she had...? The thug didn't even flinch, and yet she's able to cut down a fully-grown tree with one swipe (without the assistance of Crescent Rose's recoil), and she was kicking Grimm in the face during Vol. 2's finale, Breach.

I guess it could be assumed that it's the simple matter of that White Fang member having a stronger Aura than Ruby, thus rendering her own physically augmented strike useless. And her being able to kick Grimm comes from the fact that the Grimm lack the passive 'Aura Barrier' to protect them from her strikes.

If I may make another analogy between Aura and The Force; It's the same as a stronger Force sensitive's own 'Force Barrier' resisting the influence of a weaker Force sensitive. This is why you don't see two Force Sensitives 'ragdolling' one another often via Telekinesis.
