I’ve run Hamming circles within CFAR contexts a few times, and once outside. Tips from outside:
Timing can be tricky here! If you do 4x 20m with breaks, and you’re doing this in an evening, then by the time you get to the last person, people might be tired.
Especially so if you started with the Hamming Questions worksheet exercise (link as prereq at top of post).
I think next time I would drop to 15 each, and keep the worksheet.
