If one has mastered the form why is one still doing it. Teaching yes, but if one has already mastered it why do it?If you have mastered the
1. beginner level form,
2. intermediate level form, and
3. advance level form.
When you go back and do your beginner level form (not teach to your students), will you still use your beginner level method, or will you use your advance level method?
When the long fist master Han Ching-Tan did his beginner level Tantui form, he used the intermediate level "toe push kick (taught in 3rd road Pao Chuan) " that was not taught during the beginner level Tantui training stage.
As far as for teaching, whether you should teach intermediate method, or even advance method during the beginner training stage, that can be another discussion subject. I like to address important principles during day one.
Would be a waste of time and energy.
However, one may feel they haven't mastered it. It would be up to that individual to decide and no one else.
