I’ll make a comment here, and perhaps this is just semantics but maybe it will give you something to think about. You mentioned doing the kata “well”. From my point of view, this implies that the kata is a goal in and of itself, it almost becomes a “product” that becomes a performance. To do the kata well. Consider this possibility: the value in kata is not in how “well” you do it. Rather, it’s value is in the fact that you simply do it, over and over. There is no judgement in the kata being done well or poorly. Kata is a drill, a tool for practicing your methods. Your skill with your methods ought to improve if you understand your kata and are mindful in how you do every movement of every technique found in the kata. You keep doing kata so that your skills improve, and a knowledgeable person/instructor ought to be able to judge your skill level after watching you practice your kata, but I believe that is a subtle but important distinction from “doing the kata well”. So, in building your own kata, think about how the act of practicing that kata over and over will improve your skills. Is it in certain techniques or strengthening your foundation, or both or something else? To me, that is where the real value in kata is to be found. You just keep doing it, and your skills improve, but not as a piece of performance art. I hope this gives you something to think about.
