I always play 60 men unit size. Now imagine I have 10 armies X 10 units (60 men each) = 6,000 men. If I had choosen 120 men per unit, I'd have 12,000 men.
My question is: should I pay double koku amount to feed my soldiers in this case? Do the koku income increases proportionally depending on the unit's size?
From what I know, farm base production is invariable in each province.
