I used to know all these numbers by heart, but it's been a hell of a long time since I touched any of it.
Would anyone be nice enough to remind me of how food works? How many peasants are fed by 1 bushel per day on normal rations? What's the relation between actual bushels produced and the food value in the region stats? Is food produced every day or on set harvest dates? What are the season and weather multipliers again?
