Still methods are NOT appropriate for all people. But Basics are. Basic training is the missing part.

You do not get to calculus without first learning arithmetic. I have tracked drop out points over several years and this is where the largest drop out occurs. That is what Kung Fu is all about - practice to make things closer to perfect. Personally, I use 24 Posture Taijiquan for this. Why should I spend time starting a new student on a routine that will take them 1 to 2 years to complete when I do not know if they will stay that long.
