more theory

Every SF convention of more than 4200 people ever has been at least a 4-day con. We have no data to say, but I suspect that it's simply impossible to run a 5000-person 3-day event. It just won't fit.

Not only that but I think at those numbers there would be a severe demographic switch and the con would have to alter itself to suit that. That would change things on pretty much every level.
