I think I should back up where I think Brad was coming from. Traditional budo exams have not had a classroom style exam as part. If you could execute the technique, it did not matter how you perceive the art.
After all, maybe you had developed a superior understanding and create the next level of martia art, just like O'Sensei did.
Would we have had Aikido if O'Sensei had been required to write essays on Daito Ryu Aikijutsu and why it is the way it is. That requires you to justify the way things are done, not how they can be done better!
