"Misconception? Do you mean as opposed to choreographed movements?"
Not necessarily choreographed, thought I have done those, but also I've done flow exercises that are based around free movement. I don't think I really meant misconception. Didn't mean it to offend, was just joking about how the first pair doing the drill reminded me of a "cat fight." Generally, when I have been exposed to flow exercises it was attack, escape counter, counter their counter, make mistake, learn, continue, etc. I was remarking that the beginning of the video clip looked like a random volley of slaps, not typically following the style of flow exercises that I've done. I typed the misconception part midway through the clip and hadn't seen the rest of it yet. Later in the clip, it takes more form, as the the kind of model I talked about earlier.
Having just read the website, its called Ki Chuan Do and Guided Chaos. Also just read about the video clip, "Contact Flow." It says:
"Contact Flow is a 2 or MORE person sensitivity exercise somewhat similar to chi sao or push-hands except that it is completely free-form and anything goes (including ground-fighting). It is usually performed very slowly to maximize creativity and development of the nervous system but can be done at any speed up to and including maximum adrenaline velocity (this obviously requires a very high level of skill so that training partners don't seriously injure each other)."
