Then your thread is based on a false premise. You don't train anybody. Not up from beginner at least. You aren't a school. You don't teach. You don't have instructors, not in the sense that a regular studio does. You have coaches (you may call them 'master' or instructor, but on a team, a coach is really their function, regardless of title). The goal of a competition team is to win competitions, not teach, again, at least not in the same sense that a regular studio does.
Blackbelts off the street are not a fair representation of SD training. Who's to say that they were even really black belts? And if so, who's to say that they were not from some McDojo that claims to do SD but really is just a glorified after-school program? And your team is hardly representative of the typical KKW school that does WTF sparring and how they train.
As the details come out, it becomes clear that the healthy debate you mentioned is not what you were really after. You presented the details in a less than up front way in your op for the sole purpose of poking at one member or a small group of members on this site.
And that, sir is trolling.
