When I am asked to judge a technique I always have to ask what is the technique for? I rate Kenpo techniques in three categories. Demonstration, Self Defense & Teaching.
Once I know the purpose of the technique then I can properly comment on it. TKD perform many techniques which are for Demonstration. Kenpo perform many for self Defense, while Shotokan perform katas which teach certain movements. One has to know what the technique is for before making a comment.
