Something to keep in mind is the mention of Oden's presence in Enma and the Enma being the sword used for that attack.
It bares resemblence with Kaido saying that's "Oden's Haki" when the Scabbards attacked him, and Kinemon and the others damage him.
This could be an amped up version of that.
If that's the case, it's a bit more specific of a tool in the sense that's extremely effective against Kaido in particular.
So then making general scaling based on this would be like pushing Kinemon's attack power above these attacks from the Supernova because he managed to draw blood.
