its

5.3*1.15*32=195.04 food private
69.163*3=207.489*.94=195.04 public oil price

so if the market auto bought oil below 70 or if oil could be sold for 70 on private income floor would be the same

but and its a big but, as soon as you did either one of those oil would become just as good as food for stocking depending on the price

and oil would have to go up linearlly with food compared to the floor, which means a 0 tech strat and a 1 tech x2.3 tech strat would have similar income
