for reference for us no train people. it was stated the mayor would do 25% - 40% of the number of farms as long as there were 3 or more farms to do.
if your neighbor has N farms, your friend does Y farms, and the mayor does M farms.
Code:
N Y M %
3 2 1 33
4 3 1 25
5 3 2 40
6 4 2 33
7 5 2 28
8 5 3 37.5 *will probably be this one
8 6 2 26
9 6 3 33
and so it seems the most efficient number of facility farms is 3 with the majority of the facilities on the last farm.
