I posted a link earlier to Chois first book about Taekwondo from 1959, not 1965. Thought you might like to add it to the wiki...

Well, my response initialy is how anyone would: A. Quantify what is an "Improvement" let alone a substantial improvement; and B. What would be the answer for the same question asked about Kano, Funakoshi, Ueshiba, or the KKW.
With regard to General Choi, things he did:
1. Changged from only relying on being "Deeply Rooted" so popular with Shotokan, to having a more mobile system, even while airborne;
2. Unify and codify a system from Fragments as practiced in Korea so it could be taught uniformly on a wide scale, setting forth technical parameters for attacking tools, how to use them against which vital spots, stances and purpose for the stance.
3. Develop instructors and dispatch them throughout the world to demonstrate and teach
4. Recruit instructors practicing the root systems and have them come on board to spread the art on a unified scale.
With regard to #2 above, having trained with old time Korean isntructors the lessons were "Like this" or "Not like this" . Seldom was there an explanation. General Choi gave reasons for his methodologies, which was unusual, which is not to say that reasoneable minds would not differ about whether they agrred with him, but at least he gave reasons. He also welcomed "Good" questions whereas in other schools asking questions was often considered disrepsectful. He also employed the socratic method when teaching.
Examples: Low outer forearm Block. Block stops with thumb knucle even with center line. Other systems had it stop over the front leg. His reason was the abdomen is exposed if the arm moves further out. Leaving it there continues the protection.
Walking Stance. Lead loower leg angles rearword so kneecap is over heel. Other systems, lower leg is vertical. His makes it much easier for lead leg kiscking withou as large a weight shift.
Since his extensive text contains 15 volumes the above is certainly not meant to be exhaustive.
There are loads of places in Germany that practice the Chang Hon set and do not use the sine wave. They call themselves 'Traditional Taekwondo', but I am fairly sure they have no link to the ITF.
1. Changed from only relying on being "Deeply Rooted" so popular with Shotokan, to having a more mobile system, even while airborne;
Sometimes you have to know the system in the first place in order to understand what you're being taught. One of Gen. Choi's "Basic Principles" for stepping is: "The body must always become half facing the opponent when stepping backwards and forwards."
This not only reduces the potential that you are hit because you don't present as open of a target as you could but it also makes utilizing your hip quite natural with no need for an over exaggerated twisting. (This all assumes one is familiar with the concept of full, half, and side facing in the first place, of course.)
What is being shown in the video, however, is not technically stepping it's moving from a kick into two punches. After executing the front snap kick one is already full facing. If you were to try to get into a half facing position before executing the first punch you would have to rotate the hip and torso backwards first, thus diminishing any momentum you had after the kick. When moving from a full facing position (after the kick) directly into another full facing position (the punch) you stay full facing. Hence Gen. Choi telling him not to twist his body and making sire his torso stays full facing during both punches.
IMO the person demonstrating is doing a poor job there. The backwards motion should be negated by engaging the knee of the front leg.

Culturally, the teaching style in Korea (probably all of Asia, as well, though I only have first hand experience in Korea) and in Canada or America is incredibly different...
That's interesting. I cannot name any schools that belong to any of the ITF's - and I know people that being to all three ITF organizations - that do not practice sine wave. Even the schools I know of that have joined one of the ITF organizations have in short order adopted sine wave. I suppose if you want to get pedantic you could say that at one point those school weren't practicing sine wave but if you join the ITF you adopt sine wave. Period. That's much different that you saying sine wave isn't a universal practice in the ITF or Wikipedia, an online source I could go and edit right now to say something else if I wanted to, saying that some ITF schools adopt sine wave while others don't as if it's just an option. You might as well say some Isshin Ryu schools use a vertical fist when punching and some don't or some Wing Chun school use chain punching while others don't. You know, whatever they want to do.
As for when sine wave was introduced, GM Kim, Yong Soo, who was the ITF chief instructor at one point, said in an interview in 2005 that it was introduced in the late 1960's. I'm going to take his word on it over Wikipedia's. You can make up your own mind on the matter, of course.
Well, that's a long time. I'm sure you have a pretty good handle on the nuances of the art and its history at this point.

I would assume in any case that a truly traditional ITF school, not geared towards ITF competition (in which sine wave is mandatory) could teach it either way.
I at any rate don't concider sine wave a defining characteristic of ITF Taekwon-Do. Something which only gained prominence in the 80s...
...as a direct result of an overly ambitious, brain storming General Choi.
My school is geared towards competition and teaches sine wave.
I would guess the former as he says 'That is sine wave, don't twist".That video is puzzling. Is he saying that they should never twist their waist or that they ARE never twisting their waist?
It is the case in Australia with at least two major organizations.There are loads of places in Germany that practice the Chang Hon set and do not use the sine wave. They call themselves 'Traditional Taekwondo', but I am fairly sure they have no link to the ITF. I wonder if this is the case in Sweden.
Like TKD Six Sigma also has black belts.Years ago at work I had to coordinate Six Sigma ("process improvement") training for offices in the U.S. and UK.
It was pretty straight forward. Sorry you couldn't understand out.

Sometimes you have to know the system in the first place in order to understand what you're being taught. One of Gen. Choi's "Basic Principles" for stepping is: "The body must always become half facing the opponent when stepping backwards and forwards."
This not only reduces the potential that you are hit because you don't present as open of a target as you could but it also makes utilizing your hip quite natural with no need for an over exaggerated twisting. (This all assumes one is familiar with the concept of full, half, and side facing in the first place, of course.)

The backwards motion should be negated by engaging the knee of the front leg.
Useless in a street fight though.Like TKD Six Sigma also has black belts.
But it looks like the General is letting him fall back even at the points where the General has control...and perhaps there is something here that I don't understand about sine wave, but even if that back leg negates the backward motion, you still only have a vertical up-down motion with no vector contributing to the punch.Sometimes you have to know the system in the first place in order to understand what you're being taught.

I understand the use of sine wave for motions where there is a step forward, adding gravity as an assistive force. But on the spot as it is here, or in a stationary horse stance, I can't get my head round what it actually adds.
True or not (not), what's that got to do with rising before sinking into a strike?
And I posted some pre-sine wave ITF tae kwon do upthread as well...then, of course, there's this resounding demonstration of what I think is a complete misunderstanding of physics and basic body mechanics:
