The impression I get from reading this (and other) threads is that Kenpo means different things to different people. Depending on when, and from whom one learnt, can define a person's kenpo - be it Chinese Kenpo, Kenpo Karate, etc. Whatever you learnt, whenever you learnt it, it is still kenpo. 16/24/32 techniques, extensions or otherwise. It's your kenpo, it is correct for *you*.
The most valuable thing in the Kenpo system for me, is the open, logical approach to martial-arts which encourages people to question (with an open mind) what they are being taught. That's why I started. The instructor should be teaching the student these lessons - so that they can make informed, honest choices about where they want their training to go next.
If someone has this approach, then I would deem this 'correct' - this is what kenpo is all about. The whole motion/commercial thing is irrelevant in my opinion. So what if you don't have all the answers right away. Everyone starts at white-belt regardless of system/style/school, and as long as the instructor and students are honest about what they are doing then this is all that matters. This is the approach to Martial Arts that I believe Mr Parker wanted people to follow, commercial or otherwise.
For those that bury their heads in the sand - who cannot bring themselves to look inward and analyze what they are doing. Who go away and form cliques which attempt to discredit the work of others. For those that have so much invested in their own rank/ego/status that they fail to give honest answers about what they are doing, to the detriment of their own and their student's development. In this case I question whether what they are doing is American Kenpo any longer...sure it's kenpo, or karate, whatever. But American Kenpo?
