Has anyone number-crunched the city maintenance?

[Senethro]

SMAC player here having extreme trouble resisting the urge to grab every piece of unoccupied land. The fact that my fastest research games have been those where my expansion has been checked early by the AIs has made it clear to me that I need to do something differently.

Does anyone know how the city maintenance is affected by world size/difficulty/civ traits?

Thanks, Civfanatics has some great posts but I really hate having to wade through the spam to find them.
