In my experience, I would say no. Same as similar approaches (e.g. Waldorfschule) Once I asked some advocate of the method, what was it exactly; the reply was very good and detailed, but then I pointed out institutes that “follow” the method, which were nothing as what he described. From that point, it was a mess. “Well, you must not absolutely do it that way” “there are variations” etc. I was pretty dissatisfied with the description, and was clear that is not very well defined.
