@Bill Mattocks and
@Cynik75 Here's an example of a green belt technique in American Kenpo.
That was not one I chose specifically to highlight my point, I just chose a random mid-rank technique (per google this is a green belt technique). You should be able to see pretty easily why there might be confusion for new black belts of AK if techniques like this one should be reworked/streamlined.
It also explains why newer black belts tend to look into other self-defense systems to create a streamlined version of the system. Whether or not that's needed/beneficial is a topic I'll bow out of though.
