Interesting theory. I haven't had change to try that kind a situation. The biggest game by people was like 6 people and 2 experts.
I can see that thou. I often had to give example rules for people, thou I feel like it robs part of the fun.
With more experts it could make things better, if they go easy on start. If they go full on with super hard rules, the half attention newbies would be lost.
Thou if the newbie really wants then they could learn in that big expert play too.
