Some observations about event cost: Ranking.

For expeditions, a blatant method using weighted geometric means with arbitrary coefficients is giving me

> head(optimize(exps, fuel = 4, ammo = 1, steel = 0, bauxite = 0, bucket = 1, kx = c(1, 1.5 * 1.2, 1.5 * 1.2)), 30) fuel    ammo     steel  bauxite    bucket [1,] 2  5 38 407.2000 440.0000 207.42857 24.00000 1.0000000 [2,]  2  5 21 362.2857 619.1429  84.00000 24.00000 1.0000000

It would be nice to have a better method, so you can input your daily expenses in each resource and it will tell you that you need to do expedition X N times, Y M times, etc., then you can group them in triplets or whatever. Though, personally, I think just 2/5/21 + quests is working well enough (maybe with occasional 4 and 6, 2/5/38 if fuel takes a hit, or you want to finish that Tokyo Express quest).
