Fair enough. I find it confusing to use the same term for two different concepts. If the centerline is the line between you and your opponent, then what do you call the line that bifurcates your own body? If your punches do not travel down that line how do you chain punch? If your hand techniques do not end on that line what of structure? Again, I am not talking about aligning with the opponents center. When you shift and punch the punch could very well end up travelling diagonally in relation to your opponent, but still end on your own center where it's strongest. I wasn't aware there were strains of WC that didn't use centerline theory.
