Here's an example of how I was considering making a thread.
In a nutshell while you are blocking you initiate a command that pushes the attacker away from you to give yourself space and reduce pressure.
Typically while blocking you would push 2 Punches at the same time. (Marvel vs Capcom 2 & 3, Skull Girls)
In Vampire Savior you press P rapidly.

Then if I had it available or wanted to write one up I'd give some example coding or leave it without and hope myself or someone else adds code examples later on.
