Master Weiss, perhaps he means the difference in how one moves into the stances. In Won-Hyo you move from an L-Stance into a Fixed Stance by sliding the front foot while in Hwa-Rang you move from an L-Stance into a Fixed Stance in a sliding motion (both feet moving).
@Earl Weiss Mr. Weiss, this is something that wasn't made clear to me. Is there a significance to the ready stance "C." Besides it just being a different ready posture. It kind of looked like a flower and hwa-rang meaning "flowering youth", it kind of made sense. I could be way off and just using my imagination though.
Sine wave, for systems that use it, is on every move.
