Production Ratios

What is a production ratio?
Being efficient in the Settlers Online is not always easy, and one of the best ways to be efficient is to properly utilize what we call "production ratios." These are the balance between production and consumption of specific resources. For instance, how many foresters do you need to balance out woodcutters and sawmills, so that neither run out?

Example
Foresters -> Woodcutters -> Sawmills (Pinewood planks)

3 -> 2 -> 4

In this example you would need 3 foresters, 2 woodcutters, and 4 sawmills for optimum pinewood plank production.

Ideal production ratios
