To me that n choose 2 is more of an upper bound. If each 1-on-1 didn’t hear each other and they were not ordered then the time to do those would be the same as randomly picking people to discuss. But in a group discussion the discussion can hear each others. In a simple case where there are only 2 true factions but each faction has 50 members you could have the whole group crux if 1 member from different factions cruxed and others listened and the chosen ones were perfectly representative of their factions. To the extent there is faction internal strife you can’t reuse per se the previous discussion. The least copyfriendly case is when everything needs to be done fresh for each member in which case it doesn’ t matter if 1-on-1 discussion do not hear the group discussion.
On one hand adding additonal participant means it’s another dice throw from what random position they start from which can be in additional dimensions not yet exhibited. On the other hand each thing said can be listened multiple times in the same time frame (or reverse each listener can only receive 1/n amount of talk that is relevant to their beliefs).
