No harm done. Thank you for owning up to the error.
As to the second and third question issues:
Funny and long story which I'll try to abbreviate to answer.
Not in competition, no. I re-involved myself in full contact coaching (after taking a hiatus upon my teacher's passing) for competition in the early 90's simply because I got very tired of hearing people say that internal martial arts were not useful for fighting.
We have always fought full contact in my school, with only one rule; If you can't use a technique with reasonable precision and control, wait until you can do so to use that technique. So anything went, including ground fighting.
So I looked around at what venues had a solid operating structure and came up with only three. There was kuoshou (my personal old venue), but the rules had changed substantively so initially I kept looking. But found only the sanshou federation as it was then and they were using too much padding for my tastes. I also found the kyokushin structure. But they weren't allowing hand strikes to the face. Again, not to my tastes. So it was back to Kuoshu.
The UFC, as you may remember, was just getting started and honestly had I been able to predict how popular it would become, I likely would have made the choice to take my teams that route. But, alas, I did not have that particular crystal ball.
So initally, I pulled my first team right out of my full contact classes. They did well (one gold and four silver in internationals that year) but we lost a few finals due to "fouling" by hooking the head and hitting or neck cranking and also hitting after taking down the opponent. Which were all now illegal.
I consider myself a decent coach and always there for my fighters, so we adapted training of the teams to the venue, shifting the emphasis to that which we were most likely to deal with. The Belgians loved to shoot and other foreign teams loved to "bullrush" so from that point forward, the "teams" focused more on counter methods to those types of attempts at grappling.
I've always believed in training people completely and then having them adapt their technique to the venue, whether that be the platform or the street. But I will admit that the goal of building a winning team does require priortizing their training emphasis. And I did just that.
This is already longer than I intended and I have another session, so will end here for now with one last comment. We would transition to the ground as well when necessary. How well we would have done? I don't know. But we do work the tools.
