Hey Joe--no need to get testy! The word "myth" in reference to folklore and oral traditions doesn't mean a lie or falsehood. It means a tale that has taken on a greater or transcendent meaning within a given cultural context. Certainly many myths, especially about origins and cultural heros may begin with an actual person who's story grows in the retelling until it assumes "mythic" proportions. Think about the stories we tell about historical figures like George Washington or Abe Lincoln. Nobody really believes George actually threw a silver dollar across the Potomac or chopped down that cherry tree. As far as I'm concerned the same holds true for Yim Wing Tsun. But I don't really care if she actually beat up that bully or not. The "myth" has so much more to teach us than what little factual history we have of her and the other very early figures of the Wing Tsun lineage that Dr. Leung Ting has researched.
