I've seen it (repeatedly) being taught/described as being a "separate" art. It is (only?) another integral part of Taika's Life-Protection art.
Anyone who (attempts to) puts forth the notion that a practitioner needs to know (anything) about "TCM" (traditional Chinese medicine) to perform Tuite, is a fraud, and knows nothing about Tuite (as was taught by Taika). Whatever it is that they're teaching, it has nothing to do with, nor was it ever taught by Oyata.
Many of the people that promote this garbage have become "popular" (at least with themselves, and amongst the ignorant), and have sometimes even acquired a large following, but that doesn't make them correct.
To the (average?) casual observer (or recipient), who has had only limited, if any actual experience with Taika's Tuite, his version would always seem to create a far greater effect than would be expected. The most fraudulent of the imitator's will attempt to use "TCM" to (explain?) the increased effectiveness of Taika's techniques. But this is a misleading diversion (to whatever nonsense it is that they are promoting).
The fact is, that "they" don't (really) understand how Taika performed his versions of the techniques. Hence, they have attempted to add a collection of (their own) misleading nonsense to further confuse their followers (and be able to maintain their own supposed superior abilities).
One of their (blatant) attempts at confusing their students, is their "9 Principles of Tuite" (which are just a renamed version of their "striking" principles). This vague "list" has next to nothing to offer the practitioner in regards to the application of "Tuite" techniques.
Equally pathetic, is the recent inclination to award "rankings" in Tuite, WTF? this is merely a sub-portion of the style being taught. Anyone proclaiming to possess a "Ranking" in Tuite either is, or has been a victim of fraud. There is no Tuite "system" (it is only a portion of an entire instructed system). I've even seen people claiming to teach/award rank in Oyata's Tuite methods (Bullshit).
If your wanting to verify that someone is performing one of "Taika's" Tuite techniques correctly, have them perform it slowly. I've utilized this method with numerous practitioner's of the "kyusho international/Dillman/Moneymaker" ilk, None have been able to make their versions of the techniques even work (without speeding-up, or muscling their version of the technique to obtain "some" manor of response).
Those student's have become mislead by these types of individual's (in regards to how Tuite should be both learned and practiced). When I watch these wanna-be "mimics" of Taika (in the numerous videos that they put out), their technique application mistakes are legion.
Most notably, they (attempt to) copy Taika's manner of "throwing away" the uke (after the initial application of his techniques). This was originally done (by Taika) as an example of the motion being only a "demo" (as opposed to how a real technique application is utilized),
Most (if not all) of these people had only attended a few "seminars" (and never actually trained with Taika). Seminars only provided examples of what he was teaching (with the intent, being to recruit actual students). These people had only attended a few of those seminars (and had never actually trained with Taika).
Correct practice of Tuite technique is performed slowly, the results are (or should be) identical (to the actual technique application), but without any long term injury being suffered, Any physical differences (Size, Strength) between the tori and uke are irrelevant to the response of the uke from the techniques application (at least when performed correctly).
Most have attempted to supplement their techniques utilizing some manner of "finger" twists and cranks (to make them appear to work similar to Taika's versions). Though these changes may make the applications appear to be more painful (and may even superficially appear to be equivalent to Taika's versions) , they do not create the correct responses (from the uke) from that manner of application.
Whenever I encounter someone who questions the practicality of Tuite applications, that doubt has always stemmed from that person's exposure to one of these other versions of (what they're calling) Tuite.
To be fair, not all of Taika's actual students have always (completely) understood the correct manor of how to apply Taika's Tuite applications. Being "close" has (too often) been sufficient for many of those students as well.
Even when only watching the techniques being applied, the difference is obvious (if you know what to look for).
