Even ConCom we split and did solo. Marc and I have done a few ConCom classes each over the last year and we usually talk afterwards. It's become really apparent that we get different questions from our students. Questions coming up are a sign that something is being missed. If one instructor is getting the questions, there is something in the presentation that is less clear... so it was a good chance to watch each other talk and see what and why.
Couple of things deserve whole posts:
True value in sparring (found it!) More convinced than ever that a lot of training paradigms are crappy for what we think they are and really, really good at developing abilities we aren't even aware of.
Pre- and post-internet language and instruction. Touched on this before, but a few things have to come together to get useful insight in certain areas. Not a lot of people in any given area have a complete package. Even fewer, before the internet, wrote anything down. That's created a network of private languages and theories for similar observation. Interestingly, it's also created an etiquette that feels natural to the people raised with it.
The ConCom issues are big, even and maybe especially in teaching. Saw excellent examples of that.
Symbiotic adversaries. Take two longevity-oriented groups who have their identities based on being enemies. Neither side can ever 'win' without losing. Neither can let the other win. Even when they agree, they must highlight the differences...
Do some things need to be taught? Or is just playing with the ideas better?
And maybe a technique post, an obsolete thing that I teach because of everything that goes into making it work.
There was more. Kasey could apply the body mechanics of sword to take-downs in a tactical entry because body mechanics don't change. We used different words but all three of us talked about structure and motion and core, smooth versus staccato or explosive, damage versus pushing or unbalancing. 'Gifts' became common shorthand. My esoteric sounding 'big wave' body mechanics are exactly the same as Marc's "It's just exactly like puking, bro." Make the connections.
DTs taught in coordination with force law and local policies. Knives the way bad guys learn them. Brainstorming each class of violence from the point of view of the perpetrator. We even got some range time. Five inch pattern at seven yards. I am way out of practice.
