OK, first off, please read what I wrote. Nothing in it says that Short 3 isn't symmetrical; it says that it's the only form that doesn't begin and end in the same place. However--if we want to discuss symmetry, why then, NONE of the forms are in fact symmetrical. Nor is the human body.
Second off--sorry, but I believe it to be an error, not ending where you've begun. Please look at pages 53-4 of Inf. Insights, vol. 4, which discusses this under Short 2, and ties the concept to bad footwork during the form. I realize that will bug folks, sorry. But I notice that nobody can give a reason WHY the shift's supposed to happen. Nor does such explanation take volumes to begin.
Look: you end in the same place a) because of "point of origin," b) because it teaches you where the different places on the clock are, c) because it teaches properly-measured footwork, d) because of the concept of, "center," e) because it teaches where your "space," is and how to come back to it; f) because if you do the footwork right, it works out that way, g) the "reference point," for this form is a horse stance oriented to 12:00, with the center line of the body on the center line of the form.
If you put in the stuff I mentioned, the Rpt. Devastation part won't matter--especially because the form has the step to 12:00, not 1:30 as in the technique isolated.
Again--I apologize, please take it as simply a passionate statement. But it isn't, "all good." Not all of this is, "opinion." Nor does, "tailoring," mean changing for no reason.
Eppur si muove, folks. Not everything is right in this way, any more than all opinions have equal weight in science--you don't have to believe that the earth moves in an elliptical orbit, or that we evolved, but well...there's the prob with the mountains of evidence.
I'll try and shut up now, since I don't mean to tick anybody off. But unless I can see some reasoning...nope, not gonna buy it.
