....Oh dear. #1, no, oh goodness no. #6 I didn't know until I started learning Korean. Now people don't understand me when I say it correctly because they think it's thai-kwondo lol. #4 is good. I see a lot of the X by the head in videos but we do the chambered hand on your shoulder, below the ear, and other hand straight out.
I brought this up with an announcer for the BBC (British Broadcasting Corporation) once because he kept saying it wrong and he said "it's in the official BBC pronunciation guide that way, maybe you're wrong?". I showed him videos of the Kukkiwon and WT president talking, both said it correctly, then I replied "oh well, maybe they're wrong...". Still he had a job to do, so I understand.
But #2 is pretty inconsistent. Our school owner doesn't teach it that way, but one master does and visiting masters we've had have done it as well. I don't teach students to go up on their toes, but I do it slightly when I do my own joonbi as its just a habit I've picked up from various masters who have taught me.
Just so you know, this is consistent in Korea. It's only outside that people have their own weird ways.
#3 We do teach joonbi as slow then sharp at the end, but when I trained with a master specifically for poomsae for a tournament, he taught me to do the entire thing slowly. I know that there are "old ways" and "new ways" and "tournament ways" of doing some things so I really have no problem switching between techniques depending on what I'm doing. Even our double knife hand block is chambered and executed differently as a color belt vs black belt and switching between them when I'm teaching and practicing isn't an issue. I think I may ask my master about the joonbi thing just because I'm a TKD nerd and like to know the WHY for everything.
I'd do the same. Feel free to share his answer if you don't mind. I'd also be interested if he does a final jerk in the slow movements in Taegeuk 6, 7 and 8. The punches in T8 I can understand because it's a strike (although it's still incorrect to do so, according to Kukkiwon standards), but I'd be interested if there's a jerk/snap in the slow movements in 6 and 7.
#5 we teach forward stance as being shoulder wide. This is the first I've heard of fist-width. I find that fascinating!
The reason is that you want the weight to be biased forwards, for maximum power delivery. Lateral stability doesn't matter (during a fight/combat you aren't expected to stay in long stance position). The way it was demonstrated on the course was that the instructor had a guy in a long stance (think his was slightly wider than shoulder width, but not by a lot and I've done the same demo myself on shoulder width), then the guy puts out a punch with the same foot as hand (e.g. both left foot/hand out). The instructor then literally puts his palm on the fist and pushes towards the guy.
When the stance is wider, they always go off balance. When one fist between the inner edges of the feet, you'll have to push hard enough to lift their front foot off the floor to move them. So if you're aiming for maximum forward power delivery, why form your stance for lateral stability. Anyway, it resonated with me (aside from it just being "correct").
If you look in either the Kukkiwon Textbook or Grandmaster Kang Ik Pil's poomsae books, you'll see feet diagrams of the stances.
Color belts don't need to be perfect and I can't even justify taking points off because someone can't do something. If they do their best, that should be "good enough". At black belt, we do Taegeuk forms again and make them better, but even then no one is perfect. That's just not realistic.
I get your overall point, but disagree with not taking points off. You should take off points for things not done well/correctly. However, the pass mark shouldn't be 100%!
I can't remember if I've shared it in this thread or not (and too busy to hunt back through), but I wrote a blog post about how we score tests and I still stand by that now.
