Hourly Silver production is calculate on the following basis:
Population Limit * Happiness * Tax Rate = silverrate per hour
Example of calculation:
a) one Villa Lev 1: 100 citizen
b) Tax Rate = 35%
c) -> Happines-Basis = 100% - 35 % (from b) = 65%
d) Coliseum Lev 1: + 1% happiness
e) -> 65 % (from c) + 1 % (from d) = 66%
f) Available Population: rounddown(100 (from a) * 66% (from e) ,2) = 66
g) Silver: rounddown(66 (from f)* 35 % (from b),2) = 23 Silver per hour
