whilst i also agree with you for the majority of this post, there are some things which i feel slightly different to yourself about:
i thought that there was a banner outside Ip Man's school declaring him a student of Leung Bik, therefore this must have been either
1. True
2. Ip mans personal marketing ploy?
Although i do know that Chu Chong Man recognised Leung Bik as a student of Leung Jan according to one of his articles in New Martial Hero.
'WCK is not a system of knowledge and is not knowledge-based; it is, like any martial art or sport, a skill, and is skill-based. As such, our abilitiy to do it doesn't depend on intellectual knowledge (any more than our ability to play basketball depends on knowledge). You simply need to learn the few skills that you need to do the activity (the fundamentals). '
i only agree with this to a certain extent, but if you imagine,say, the best boxers of the times throughout history many of them where head and shoulders above their competitors in terms of intellect too - Roy Jones Jr springs to mind, and of course Mohammed Ali.
