Good heavens... I thought no one would ever notice the different ideas on what a "cross" is and how it works. I'd given up hope, in fact. On the one hand, there is the traditional view of the body in relation to ki, etc., and on the other hand there is an X-shape. It'd probably be a really good idea to sort out how the body works when ki/kokyu/qi/jin forces and body training are involved. I realize you said "there was a discrepancy", but I think it's worthwhile to think about how things work. It would be productive, in my opinion.

FWIW
