Steve, I am assuming things, but you don't sound like you've ever run a school or taught a class for a period of years and have advanced students to the rank of black belt. IMO, it's really not as free-form and spontaneous as you make it out to be. There are certain skills that must be acquired before higher level study can be undertaken and this takes time to achieve or develop. Some are talented and can reach this stage quicker than others can obviously. But it is not a case of a giant like Isaac Newton lapping his peers. Negative. With regard to martial arts, beginners fall into the same time bands for progress.

I don't teach martial arts. I have, however, been involved in training people for most of my adult life. The art

)) of teaching people to do anything is the same, regardless of the activity. While it may look different, the mechanisms behind good training are consistent. Bad training, too. People only learn in so many different ways and good training is repeatable and very predictable.
I would never say that teaching people to be experts in something is free form or spontaneous. I'm saying exactly the opposite. It's deliberate, measurable and predictable. You appear to me to be arguing two sides of the same coin, which is, frankly, confusing me. You're arguing that something is arbitrary and subjective but then suggesting that I'm the one who's free-form and spontaneous. I don't get it.
One of the real problems I have with the way that most people represent martial arts is the idea that it is somehow different from every other thing we do. It's not. That's just ego talking.
Martial arts training is a physical activity sometimes combined with a philosophical component. There's a what and a why.
All artists are subject to external measures of skill and talent. There is, contrary to the beliefs of some, bad art. Bad poetry and bad paintings. While there is certainly an element of personal taste, there are also objective standards. Symmetry, alignment, color harmony. There's a vocabulary used, and an educated person can look at a piece of art and make observations.
Even on a website you can see elements of art. How it's laid out. Where the eye goes. Tension. Contrast. Why a person chose a serif font or a sans-serif font. Font size and color... These are all things that an art director is trained to comment on.
The point is, these things aren't subjective. A good writer knows and understands these things. A good graphic artist does, too. The point I was making earlier is that some people know these things inherently and others learn them. But they're observable.
If you truly believe that you're training artists, but can't articulate the minimum requirements in terms that aren't arbitrary, that suggests to me that you don't really understand what being an artist actually means.
Anyway, it's clear that we disagree. We might just need to leave it at that.
