Luckily I can guess what P.I.T.A means :)
I get the point and understand your logic for using ZPG but I also note 3 of those cities are losing money. That's my problem. I'm fond of the filthy lucre and the best way to get it is via large cities. Tanais above required 20 peasants to keep it happy even before 24000 and, to give you an idea, even at 30000+ with 20 peasants it is still making 700 a turn after 1300 corruption. I'm hoping somebody out there has some magic bullet I don't know about for getting rid of those annoying peasants - I'm never happy if I have to use more than 3.
I think governors are one of the few weaknesses of the game. Leave one in a city too long and the negative attributes it gains will eventually make it worse than useless.
