I think the answer is education. Someone in your state association, if you have one, needs to pick up the poomsae officiating ball and run with it. Maybe someone like Richard Sacks. I believe I saw him at the Kukkiwon Hanmadang IR seminar a couple few years ago, so hopefully he understands what the standards are.
I think in Texas Raymond Hsu was trying to run with the Poomse IR chief obe-won kinobi. I liked Raymond, but not my first choice for P.O.C. for poomse in the state. And a good reason why Texas Poomse is behind the rest of the country... no offense ment, just My Opinion and opinions are like..... i know.
Ok dirty dog you are right and I have that same set of videos, my question is this when and why the changes? In the picture version it shows the front of the knee and the solar plex, to me this is the right way so why is the video different? Well maybe someone will be able to give some sort of resonable explination for this.
I was taught this, The first kick to the Knee, the second was to the head, HOWEVER keep in mind the head would be around shoulder height after the kick to the knee when they bent down from the strike. It was always a matter of interpretation of an equal sized opponent of the same size as the person performing the form. ( I know... we all know that) Having said that, A kick to the sky I THINK started to show off certain persons flexability and get a WOW factor.
The 96 version of the KuKKI textbook (english reprint of 73) says double yop chagis, first Arae, then Momtong, the pictures show a kick to the Knee, the a shoulder high kick, yet under the Application section it shows a kick to the knee, then Solar Plexis (mid Body not waist)... I think too many focus on the pictures, The first Taeguek book I had was By Pu Gil Gwon and it said the same, Another book Later By GM Yeon Park say Kick low, then second to Body but showed a kick to the knee, then waist.... perhaps that was as High as he could kick or perhaps that was where GM Park felt the most power from his kick.
In the current Kukki Video's in the application part they show a kick towards the Knee to stop the opponents Kick, then a Kick to the head...
Soooo... in the Kukki printed material it seems it has never really changed and always seemed to keep it around the upper body to head area, but in the spinoff american "interpretations" the second kick is close to the waist and up....
Perhaps the differences came from many refencing the american WTF endorsed versions instead of the KKW printed material...
also, for what its worth, not much time was focused on Koryo, just a generilzed area of contact for the kick then we pressed on. They were more concerned with NOT kicking in the same spot or kicking the floor then the sky....
