Ratios for Simple Science buildings

Unlike most buildings, the science system buildings clearly weren't created with synching production times up with the buildings that feed them. Some numbers can still be worked out for them though as guides.

From left: Storehouse, Finesmith, Simple Papermill

Finesmith needs 4 copper ore to make a nib, and has a production time of 15 minutes. Copper mines have a production time of 3 minutes, but you need to take into account that they need to do 4 trip (thus 4x walk distance) in the time the finesmith only needs to do 1 walk. If your copper mine needed a 24 second walk, they would pluck 4 ore out of the ground in 13m:36secs.

So if you have 1 level of copper mine for each level of finesmith, your copper will come in a quicker than the finesmith uses it, but will only be quick enough to drop to 4 levels of copper mine for 5 levels of finesmith if your mine's are very close to storehouses.

The Simple Papermill uses 2 pine logs and 2 water to produce a piece of simple paper every 10m:30secs. At that pace, it only winds up needing around 260 logs over the course of a day.

A level 1 pine cutter brings in around 700 - 800 logs a day. It uses up somewhere between the amount of logs a sawmill uses and a coking plant. 

If you wanted to have that many mills, the  ideal ratio is 2 cutters : 3 foresters : 3 papermills.

Otherwise, 2 cutters : 3 foresters : 1 papermill : (2 sawmills/1 coking plant) would work out alright with a small log surplus.

For water, a level 1 well brings in 350 - 400 water a day, your papermill is going to use around 260, so 1 well easily feeds it.

So at the end of it, the ratio for finesmiths are 1 level copper mine : 1 level finesmith, although with copper mines sufficiently close to storehouses, you can have 4 levels copper mine : 5 finesmith.

Simple papermills are: 

1 papermill : 1 well : 2 cutter : 3 forester : (1x coking plant/2x sawmills to use up the rest of the logs).

for a lot of paper

3 papermill : 2 well : 2 cutter : 3 forester.
