That was a really interesting blog Victor, thanks for that. It was thought provoking regarding the different versions of Gichin Funakoshi's book you came across! Makes me wonder how many other books by masters from days gone by have had their content edited by other people.
Your blog also made me wonder about another point: Is less more? Yip Man Wing Chun is suppose to be a simplified form of something that had, once upon a time, a lot more movements and forms. One of the lauded benefits of modern WC is that it is much easier to learn than more complex kung fu styles.
In the same way, could it be that modern Shotokan, which excludes some material that Gichin Funakoshi taught once upon a time, is easier to learn? Is it better to focus on a smaller amount of material in order to increase the likelihood of mastering that material? If I focus on the 100m sprint instead of a decathlon, I may not be as well rounded, but my sprint should be much better than if I trained it as part of a decathlon, no?
