@maxdancona,
I'm curious about something. (Note that I have not bothered to watch the infamous 9 minute video.)
Earlier discussion from some months ago made it sound like the guy was on his side and the knee pressing on the side of his neck.
Recent discussion made it sound like the guy was on his belly with the knee on the back of his neck.
Is it clear which of those scenarios is the case?
I'm not sure if it even matters. I've just noticed that recent discussion seems to describe things differently than what I had envisioned based on earlier discussion.
