The math here for corruption would be 1 * .999^540= .58

So one dollar stocked now would be 58 cents end of set, assuming 2 billion dollars are already stocked.

Buying a bushel for 42 and I get 1 dollar stocked becomes roughly 74 cents. Even at current price of 49 I get 1 dollar stocked becomes roughly 63 cents. Edit(These numbers are even better, I forgot you can sell bushels on PM now)

I'm not sure what blid (and now I) are missing. But Xin is a smart guy so I will think on it.
