However talented and skilled the disciples of famous masters may be, they are not their teachers. Each practitioner approaches the training with a uniquely personal perspective and set of physical attributes which influences their stylistic interpretation of the training material and techniques, as well as their ability to effectively execute its fighting applications. Even if one is fortunate enough to actually be taught the indoor training methods used by a famed master to develop and maintain their expertise, most students won't seriously practice such methods in the same way the master did anyway.
Instead, they will modify and edit the training material and methods to compensate for their own lack of sufficient motivation or ability to 'eat bitter' like the famous masters did. This is a phenomenon which plays out again and again in all popular martial arts in every era. That's just human nature to seek the path of least resistance as the easiest way to success, but a path that generally results in making too many concessions to the earlier training systems responsible for the skills being sought.
