Master Black Belt
I was introduced to checking back in the FV days. It's not something that is readily taught thus far in my USSD training, but will be discussed if asked about in the proper arena. Problem seems to be that not all instructors have enough knowledge to even know about this themselves.
Why is this do you suppose? Why are the instructors not taught this stuff? Could be a couple of things IMO. One: It's not commercially viable to teach to that level and so the only ones that have that info and training are the old guard. Or Two: There is intentionally information held back so that the Masters look good when they demo on the students. that is, they teach the basic curriculum to the general public and keep other more effective training to themselves so that they can keep one up on those below them. this would include the instructors at the various studios, many of whom were not even trained in SKK before opening a school (Cynthia Rothrock for example).
