I'll toss my own scaling ratio onto the pile, simply to record it and for those who might want to use it.
So. I took the approach of wanting to have +1 [resource] for every possible thing at once, balancing every job around that principle. That led to this particular ratio.
- Lumberjacks = 37
- Stone Miner = 6
- Clay Digger = 12
- Clay Baker = 11
- Hunter = 48
- Tanner = 3
- Coal Miner = 20
- Torch Man = 12
- Iron Miner = 8
- Iron Smelter = 7
- Swordsmith = 2
- Explorer = 3
- Mason = 1
- Sergeant = 1
- Food = 76
- Peasant = 1
- Total = 248
Following this ration ensures that you'll always have an equal growth of every single resource at once. It might look a bit messy, but it works.
Edit: forgot to include Food, Peasant, and Total values. And with that, I have a completed ratio that allows for equal growth of all resources at once.
