For MatB,
The latest Shimbun talked about a Karate Triangle - I believe that the Karate Triangle does not show the practitioner that there is a goal to our training. It simply shows that you start training in Kihon, progress through Kata to Kumite and start all over again. After some mastery, the three topics inter-relate in the Karate Triangle, but don't serve to achieve a goal.
If you picture a diamond (or a matrix), and external to the Karate Triangle are your goals, you get to correlate what your training means and why you're doing it.
I think I mystified some people

on the other chatgroup, but I firmly believe that Kihon, Kata and Kumite can't adequately answer all the questions in the World about Karate and self-defense on their own. In reality, the goals will change for different people (as stated by someone else - Zubs!) - for me the goals of a Martial Art should be combative technical application of what you've learnt; be it self-defense, assassination (Ninjas

, special forces), outright attack (Samurai, infantry) etc. For us, it's self-defense, so I stated that the Karate Diamond was the Karate Triangle with an extra bit added to the bottom of the triangle to form a diamond and related all the elements of Karate to our goal of self-defense.
The inter-relation contained two-way arrows to indicate feedback between all the elements, hence preventing the need to continuously cycle through a training regime - any improvement in one element would surely improve the others. Hence the idea of a diamond, matrix, whatever shape it takes!
However you wish to picture it, I don't mind one bit; but I don't see the triangle as the whole story.
My idea is still a work in progress in my mind, and hence, I enjoy the scurtiny of the idea and its value. If it does nothing else other than make people think a bit harder about why they train, then that is enough for me - otherwise, we're just drones!
