There have been several (failed) methodology's that have attempted to promote their own "principles"(for this purpose), but each have only amounted to being a vague "List" of (general) procedures that contain no actual guidance within them. Our "6 Principles of Tuite", are (at least) specific in their execution and use. Their utilization is done in unison, so this will require that the student understand their individual application within the specific techniques.
This will (in turn) require that the student understand what/how the aggressor is "strong" and/or "weak". Muscle strength is (or should be understood to be) a "non" factor. Within each of those examples (on the videos), the aggressor/uke's arm is "straight". This is the most difficult position to apply a (any) defensive application (upon the wrist, as it is being demonstrated within those videos). To further complicate the intended technique's application, the tori draws the aggressor's hand/wrist to their own chest (prior to attempting to applying the intended technique). They have "created" a muscle dependent application. The aggressor hasn't been "broken-down" or debilitated (at all). This is a demonstration of "muscling" a technique, if/when the tori is smaller than the aggressor, this will place them at an (extreme) disadvantage (and serves NO purpose in regards to the application of the technique).
Within each of the chosen videos, the person's who attempted to "explain" their applications failed to address numerous issues within those applications. They (all) basically presented a manor of using their hands, while an aggressor was pushing at them. What little detail that was provided, was more often than not, incorrect in the majority of the conclusions made in their regard.
Prior to their deletion, there had been numerous query's in regards to technique application (within those videos). None of the aforementioned videos addressed (any) "specifics", and what was demonstrated only illustrated their lack of (any) awareness that existed for them.
