Personally, I donāt find it difficult to recognize value when I see it, without the need for someone to āproveā it with a competition win/loss record. I can look at the methods, understand the logic behind the methods, look at the training intensity, and see where the skill is built. I can then decide if the training approach is a good match for me and decide if I am interested in pursuing that training. None of this hinges upon seeing a competition record.
Whether or not someone competes is a personal choice. The instructor and the students in a school may simply have zero interest in it. They may be at an age where competition no longer makes sense. None of that matters to me because I donāt need to see competition, in order to recognize value.
Thatās just me. Oneās mileage may vary.
You don't, you are also an expert martial artist with a lifetime of experience.
Not everybody in an art needs to compete, but there better be some regular feedback into the system telling it how other people are fighting, particularly when many participants of that art haven't been in regular street fights. Participating in the larger marketplace of ideas forces an intellectual honesty about the art, isolating the practice of the art away from others is a great path to delusion and irrelevance.
