The proof of the pudding is in the eating.
Why would anyone care about the competition record of a potential instructor? Presumably, because they are looking for proxies that would indicate or implicate ability for providing valuable service as a coach or teacher or instructor.
So the real important thing then, the important thing you really care about, is the quality of people they can produce (which may potentially include yourself), yes? And if you actually had actual examples of people they have already produced theretofore, that would be the clearest signal of all, yes?
Well then; a strait forward question, with a strait forward manner of verification: what are the comparative records of people whom Danaher has Produced? What are the highest achievements people he has produced attained?
