Hmm. I can see this point but I do think now we are moving out of Budo in general and more into teaching and pedagogy. I teach for a living, online college Professor, and have formal training in the area. I also do curriculum development. Just to provide background.
That's all fine and dandy, but I believe that these two fields of study don't have the same type of commitment.
The first is Stopjutsu which for me needs to be stopped up front. The logic here is that it is a "fatal" or near so flaw from a combative standpoint.
So is "allowing" anyone to perform a killing or maiming technique on oneself, if you go to extremes.
To be a bit blunt, I don't consider that to be much of a threat unless the people involved are really stupid. But then again, if they're that stupid, they're also probably too stupid to understand the usefulness of kata practice, and as such probably won't spend much time in the Bujinkan anyway.
I have a friend in the Buj who's worked for several years as a bouncer, and has also done guard service in the subway. He has basically the same problem as I have in that he can't always make decisions on how to do things in practice, and usually has to see things demonstrated more than once in order to replicate them.
But it's easy to be fooled by that if you haven't seen him in action; not only does he perform well under pressure testing such as grappling or the aforementioned "Nakadai sparring", I've seen him handle himself several times in real life against people under influence (though I don't think he's aware of the fact that I was present during those times), and he moves with total confidence in himself, without hesitation.
When I train with someone I've never met before I often purposefully stop at times in the middle of a technique to see if he'll use that opportunity to counterattack "off rhythm". If he doesn't, I see that as a good sign, in that he like me is there to train and learn and not to be a jerk to people. It signifies that he too probably appreciates a moment or two to re-think his movement strategy instead of rushing everything.
After a couple of years of observing Bujinkan discussions online, what often strikes me is that people often seem to make the assumption that things can be learned much quicker than what has been my experience. I however tend to keep one thought in my mind as often as possible - that the reason I can do this so easily (or the opposite) may very well be because I have missed or misunderstood something, or that the person teaching me may have done so.
