The use of the Lee quote in the article is strange.
Of all people, Lee would never say to practice 10,000 times in exactly the same way ... and definitely wouldn't suggest doing so 10,000 times on a punching bag, seeing as Bags Don't Hit Back [0].
Lee obviously meant "the man who has practiced one kick 10,000 times" in varying conditions, with varying timing, energy, and motion ... not in a single dead pattern.
