I've seen the Rules of Application that these people use in regards to Tuite. They have 10 of them, and my opinion of them, is that they are (like all the rest of the TCM nonsense) misleading, irrelevant and a waste of time. Of those 10, there is only 1 that is even similar to any of ours, and ours amount to only 6 Principles, and each of them apply (in varying degrees) to every tuite technique).
Their (version of) application principles, are only self-serving (for their lecture tours). They do nothing to aid the student's with the application of Tuite techniques (and in many ways are misleading). If these have been (somebody's?) standards for tuite application, it no wonder that the performance of tuite is as poor as it (obviously) is.
