I didn't account for gearbox inefficiency and manufacturing tolerances, so the numbers aren't anywhere as exact as the displayed values might suggest. So it might actually be closer to your "napkin" 180. I left the displayed values as-is in case anyone wanted to play around with the calculations and compare them.
