By the way, for this to make sense, you must think of your units as your stockpile. You are selling your units to the public market at $240-250/NW during the last week to cash them back at maybe $100-$163/NW (And this $100-163/NW already takes into account their upkeep, because it IS the upkeep to cash that 1 turn.)

It's the "commie way of reselling".
