I do my form for tournament, so it would be nice if I ended where I started. I am not about to do any of my stances wrong, though. but even for tournament, ending up off your starting point does not seem to be that big of a deal if you do the rest of your form well enough. The problem is if you are competing against someone who is just as good as you are, how far off the starting point you are might be the determining factor (referencing Earl Weiss's comment here).
Any way you can post a video of you doing the form? I'm sure Master Weiss or other Ch'ang Hon practitioners could help.
