No, it's about a third of that. Or a fourth if you use HSD. A $50 crack is enormous. Calculate the gasoline and diesel spreads separately and do a 2-1 weighted average in favor of gasoline. Use the the second and third calculators on the cme link you posted instead. The first calculator is incorrect. Furthermore, you can't just multiply the spread by the throughput since refineries don't make just gasoline and diesel.
