Well if we're ultimately serious about this, we'll want to get some physiologists invovled.
For example, someone like Patricia Cowings:
She's apparently done a lot of work on biofeedback and how it applies to motion sickness. Namely, her method gives people control over their typically autonomic functions. This is a method that NASA uses to train astronauts.
Having awareness and controlling the functions isn't enough for our purposes because we have to strengthen things as well. But, learning to control and feel it , would be a start. And learning to dial that in (by taking instrumented tests) would be a huge jump.
It's the only way that people who started practicing late in life (aka all of us without a koryu teacher as a childhood mentor, or who didn't grow up in Chen village) can get exceed those of who came before us.
