CVV sounds like the same drill but its close to groundfighting in that you both are on the ground not kneeling hips on the ground. But as you mentioned you roll up quickly never staying down to ground fight. Being that you have broken a limb, smashed his face into the ground and stabbed him in the eyes!! Whats the use of choking him out or anyother manuver unless you want to go to jail.

Sounds like the same drill. If thats Tegumi I wish there was more in Karate, but really thats just old style Goju-ryu Karate which is known and documented to like to grapple.
