I need about 200 million to build the next city and get it up to the level of the others. I make about 10.9 million every day. So I either wait 20 days or I attempt to up-sale resources to make an additional 1-2 million a day, on the risk that I lose 300k if I misjudged. Doing that takes about 3hrs out of a day. So I am left with a choice wait 20 days while doing nothing, or wait 12-16 days. Assuming I ain’t attacked
