What do the Taegeuks have to do with sine wave? Sine wave theory, for what it's worth, may be applicable to ITF forms, but I doubt it can be applied to the Kukkiwon forms. The Kukkiwon forms are a separate entity. One of the reasons, to me, why Kukkiwon and ITF should stay separate (in other words, pick one).
It was used as a comparision to the Tuls and since the TG are so simple they cannot be misunderstood. Nothing more, it never said they had the swine wave in them. Since the General was misquated alot of the time at seminar because people did not understand or refuse to understand. The TG could never have those problems.
