Except for the fact that she would be significantly trained, and have plenty of experience performing that technique against a wide variety of people.
Just curious; How many times have you actually dislocated your classmate's knee with a side kick? How many times have you slammed your bladed hand into your classmate's neck after you dislocated their knee?
If the answer is none (and it IS none because you guys don't even spar) then you've never actually done that technique. You have a hypothesis of what you believe will happen if you're in the position to do X and he's doing Y. You have no concept of the various effects that your attack would have depending on body type, weight, height, power, etc.
On the other hand, I've actually done minor inner hooks on people hundreds of times. I've done modifications, I've done proper technique, I've done combinations if the person doesn't fall the way I want them to, I've even done them in MMA gyms where the guy is punching and kicking me. I've done them against big guys, little guys, women, young, old, etc.
That's the difference. There's hypothesis and theory, and there's application. If you've never really applied the technique, you can't speak to its effectiveness. You simply have a model of what its supposed to look like.
Well as I stated before, Renzo's school produces excellent practitioners and instructors, so if she was looking for a good jiujitsu school, I wouldn't hesitate to point her in that direction.
Does anybody spar according to you? XD
I see you say "You dont even spar" to people every now and then and they usuallyu DO...
RTKD actually put a video on antoher thread of his school sparring XD
