Hello Flyboy2002:
Forgive me I cannot resist your ~challenge~.

Though I too am uncomfortable with the chi idea, solely because I have no cultural context for it. Were I of/from a culture where chi/ki/ was a daily idea, this would not be a problem for either of us I suspect?
Lets get to the heart of the issue. What/how do you classify zero variation externally, the literal carbon copy
doing a move/movements and producing tangibly, (ie radically) melo-dramatically more powerful physical results??? ie One person doing the same externalized movements yet attaining radically different results because of something they are doing mentally, or using imagery, with no externalized difference?
What/how do you classify a different mental focus? Example instead of concentrating on the situation/technique at hand, you strongly concentrate on the images, components, necessities of cooking a 5 course dinner and only that, or the mechanics of flying an airplace instead of the physical situation before you. If I concentrate, (igonore the physical in front of me) and focusing instead on an irrelevent situation... we get very different degree of power. Now instead I now focus solely on the assorted images to make a limb/joint more powerful...

What would you call that result prey tell?
