You almost made me doubt my calculations. Checking again, 193M is about $230 @ $1.2/m rate which is 205 euros. Lets just say it was @ $1.1/m rate, it would be 190 euros which is equivalent to market price. Right now, the "big" gold merchers are buying osrs gp for $1.15/m. You are assuming $0.9 is 1M.
80% of market price would be about 150M.
