It's often stated that efficiency is a core concept, perhaps even the core concept of WC. But efficiency can mean a lot of things. On another thread, LFJ pointed out that it is not the same thing as effectiveness. All Martial Arts seek effectiveness, yet not all stress maximum efficiency. Effectiveness is "getting the job done", while efficiency is "getting the job done for the least input". But that can mean many things. It isn't just "getting the most bang for your buck" or "the highest mileage". There are many kinds of efficiency. There's the efficiency of time, the efficiency of movement, the efficiency of energy, and even the efficiency of training methods. All are, to some degree interrelated, and all are considered -- at least in my WC/VT though all are not stressed equally. In my experience, the emphasis and understanding of "efficiency" what it is and how it should be achieved varies a lot between WC/VT lineages and branches.
So what is your concept of efficiency?
