ok, i'm calculating the terrain bonus for income
about mountains i found it to be 0.93, it seems right.
but i've a problem for a farmland land
9330 pop, 9 unrest, -2% scale modifier, 100% tax, no fort,income 76

(pop/100)*(scale modifiers)*[1+(fortadmin/200)]*k/[1+(unrest/100)]
(9330/100)*(98/100)*]*k/[1+(9/100)]=93.3*0.98*k/1.09
82.9*k=76
this means K<1 but it's impossible because farmland should have high resources, leading to a K>1.
Any ideas?
