Each size should give more than the one before, i.e. a tiny mine will make 1 ore every 60ticks so should a a small mine make 1 ore every 40ticks, a below average should make 1 ore every ~26ticks.
You should put in a "grow base" as long as it isn't a whole kingdom, which makes it self sufficient. Each size should use the same amount of "grow base" in different speeds. Standard should be based on tiny village (the smallest working thing) with one "grow base" for 10 in-game days, i.e. 24 000 ticks.
