KL22 is a "spin off" from Ku Lo Pin Sun Wing Chun that was created by Fung Lim. Fung Lim had an extensive background in other things before learning KLPSWCK. But he sent his son, Fung Sang, back to Ku Lo village to study rather than pass on to him the KL22 point system that he had created.
But you be the judge. Here is Dr. John Fung doing his thing:

He may very well have "personalized" things quite a bit, because here is KL 22 from China:

Glenn, let me characterize the KLPSWCK body mechanic a bit from my experience:
1. Medium width stance in the YGKYM with the heels no wider than the shoulders.
2. The pivot is on the K1 point of the foot, at the middle just behind the ball of the foot.
3. The weight is kept 50/50 throughout the pivot.
4. The stance is very upright, not hunched over or "hollow chest" like in Southern Mantis.
5. The waist or "kwa" is used for power generation and not "locked in" like in many WCK lineages. The "four directions" of typical southern CMAs are used: Swallow, Spit, Sink, Rise.
6. The waist action leads the pivot, not the knees.
7. Techniques like Tun Sao, Lim Sao, and the Got or "cutting" version of Bong and Gan are used much more than in most Yip Man lineages. In fact, from my experience Yip Man WCK hardly uses them at all.
So I'd be interested in hearing how this compares to your system Glenn. Overall, I think KLPSWCK has more in common with Yuen Kay Shan WCK than it does with Yip Man WCK. Which IMHO, kind of puts a wrench in some of the history theorizing that has been done here.
