1. The ITF is an organization or organizations that set technical parameters according to the Chang Hon system they follow. There is no such thing as "Kick X in the ITF" Such a mistake makes the same terminology distinction as using the specified English term for the Korean Term vis a vis the term being "Turning" as opposed to roundhouse, and if anything the "Turning Kick" would rarely be used in sparring, it would more likely be the "Side Turning" if accepted Chang Hon Terminology were to be used. 2. Perhaps someone else can find the reference in the text, and perhaps I will locate it later, but the idea of modifying or adapting techniques for sparring from their technical / pattern aspects is addressed by General Choi. This is evident simply by watching how ITF people punch while sparring. It would be hard to find the classic / pattern / technical stance -punch in a sparring match. 3. Many kicks "Do not exist" in the Chang Hon system if you consider that non existence is proven because it is not shown in General Choi's texts yet they are easily found in sparring. A common example would be an offensive "Hook Kick" with the lead leg or rear leg turning forward. Only Reverse Hook Kick - turning rearword with the rear leg is listed.
