Weather original comment was about an art, not techniques. You are correct that armbar evidence would be evid nice for a similar armbar in any system. That doesn’t change that it’s easier to find evidence for Judo than for NGA, for example. The techniques that we share, the evidence is universal. It’s even arguable that similar techniques can borrow some credibility. You are not incorrect. But what you are refuting is a claim I didn’t make.
