Sorry guys, just an information... Before to expand the arena is not better to raise at the maximum level the tickets and only when your arena will be full at the maximum ticket, then expand it? Increase the places is very expensive, that's why I ask your point of view. Thanks.
Very good observations. Your technique will give a reasonable approximations of some sort of optimal seat distribution. However, the experiments should be done @ a given price level. We cannot assume that price affects different seat levels at the same time. In fact the rules claim that it doesn't! /elboss
