I see where you're coming from, but imo you might have the elitist thing backwards regarding where it's originating....

Exhibit B, OP's RNC escape.... she clearly forgets to re-stomp the groin, rookie move.

No not a RNC. I wouldn’t use an elbow to defend that since after I pulled out of it I turn and have their elbow right their at breaking level if I did it right. Lol Krav is brutal I meant just the basic throat grab both hands. Where you pluck and throw their right hand into their groin as you step sideways and then turn into them with the number 1 elbow then grab their shoulder or Muay Thai clench them while you deliver a knee or 2
