@drop bear semi related question to what you've been arguing. Basically your argument is that if something X teaches works for the street, the proof is that it works in competition, right?
So let's take me. I trained under professional kickboxers. They taught me with the assumption that I would be engaging in competition, just as they did. But my first 3 fights fell through, then I had concerns about CTE so I never competed. I learned from people who did prove that what they did and taught worked, so if I were to teach what they taught me/what I trained, despite never being in a formal competition,
1. would you consider what I taught valid or invalid?
If you'd consider it valid, let's say I taught my future son how to fight, using the techniques taught to me. However, he also never competed.
2. Would he be able to teach, despite the techniques that I taught him that were taught to me were used in the ring by professional kickboxers? Or would you argue telephone rules and discount his teachings?
3. What if he used what I taught him in the ring, and one some fights?
4. What if he used what i taught him in the ring and lost some fights?
Now let's say you knew some additional information about me. I have been in many fights-in the double digits but I'm not sure the exact number. Of those, at least one trained in kempo, idk about the rest. I won all of them. Even though I had never been in a ring fight, would that give me the ability to teach others for self defense? At 10+ fights, I feel like that would develop consistency for self defense, but I don't think I used the same moves in any of those fights for consistency of those moves.
5. With the knowledge that I've been in that many street fights, and won them all, would you consider what I taught valid? And would that change your answers to 2-4?
