Paul usually teaches and it mostly consists of positional sparring rounds. 1 to 2 minutes top / bottom for a particular guard or pass starting in the position and then resetting for a pass, sweep or submission. Also starting in the positions you named along with back control. You do two rounds each top / bottom and then switch partners and do multiple rounds of that.

I think that's a way we can work on specific positions but also a way for the instructors of knowing where students need work.
