While VT is not Tai Chi or Yiquan, both have similar slow movement training methodologies. It is more limited and specific in VT, more general and extensive in TC and YQ. People who are very good at Tai Chi and Yiquan continue slow movement training as long as they continue training, same as in VT. There is a specific reason for it. If you are interested in these systems you train it and continue to train it.
So you agree that I am right?
Slow movement training is not on the table of discussion, the discussion was why it was done insanely slow by YM. You say the only reason or at least the only real reason for doing a slow movement is to train elbow structure. I am wondering how this can be your logical outcome given that A) elbow structure is already as good as it gets, B) once elbow structure exists, your time is better used to train other areas. At least rather than spending hours (!) doing SNT once.
Or you are saying the optimum way to train according to WSLVT is to be doing SNT for hours at an end? At least if assuming it is all for becoming a better fighter.
Assuming that the logical goal of training so slow by YM was a meditative state, would it then be more logical that YM with age would attempt to perform SNT even slower while maintaining a constant perfect form to achieve a higher meditative state and at some point unlock a deeper understanding of his own muscles and movements.
Or are you saying that he was not after stretching joints and adapting muscles to a good elbow structure but rather to improve it through meditating on how every muscle in his body moved each instant? In such case one could argue that you are both correct in that it could be meditation as well as elbow structure in one.
But to stretch your joints in order to maintain a good elbow structure, if you can´t after some time have a good elbow structure due to limitations in your joints.... you should NOT stretch those joints. It is more likely you injure yourself because your body may have other problems such as internal scars preventing you from doing the movement you seek.
