I wouldn't worry too much about over expansion. First of all, go through the top teams in Div 5 (not just in your Div all Div 5's). See what it takes to sell out luxury boxes at 400. I think the number is 17 seats. Then build 15 more luxury boxes. That will cost $240,000 but after you do that you will not have to worry about pricing or building anymore until you are out of Div 5. Do the exact same thing with courtside seats. It will probably be around 300 seats.Once you have those two expanded fully, you can forget about worrying about pricing vs expanding. Since those seats also are the most likely to sell out each game, you will get a stable income from the expansions.
