Here's the way it works:
So one wheat farm in a central or southern province can feed 1920/6 = 320 people per year, and all other farms can feed 960/6 or 160 people per year.
The first step in distributing food is to make sure that the entire crop gets from the farm to a granary. In the northern provinces, grain grows at the same rate as other crops. All farms should, therefore, be within 30 road squares of an "accepting" granary.In the southern provinces grain grows more rapidly and wheat farms must be within 15 road squares of an accepting granary.
If your accepting granaries are near your consumers, then it's up to the nice market ladies ( who get food only from granaries) to pick up the grub and get it to your folks. If you have some distance between your granaries and your consumers, then you have two ways to go:
A - You can build an "accepting" granary near your consumers and let your farm cart pushers truck it on over. This will work fine provided that you have plenty of farmland, money, and workers. Otherwise....
B - Build a granary near your consumers and set its special orders to "getting". The advantage here is that the "getting" cart pusher can transport up to 8 times as much as a farm cart pusher, and your farm guy is freed up to deliver more food to the local granary.
Since I don't really have a life, I have spent hours watching cart pushers. I have timed them all - farm carts, granary carts, warehouse, workshops, and it seems they are all equipped with the standard model XXXII roadcart. This cart when operated properly, can reach speeds of up to 576 road squares per year. (This does not take flat tires or freeway closures due to jacknifed big rigs into consideration)
I made these measurements by placing two points 30 squares
apart, and then arranging things so that a cart had to make round trips between
them. In every case, I came up with roughly the same number - 9.6 such trips
a year. So my calculation is 9.6 x 60 = 576.
Should anyone be able to prove overwise, I would be delighted to hear from
them. All we want here are the facts.
