Another math genius. Even if you took it to mean +50 after tonight (when it clearly says next Monday), only 13 units were wagered. If you expect 13 units to turn into 50, then I'd fire your 2nd grade math teacher.
I can read quite well actually and yes, I cleary saw that you said next Monday. I was refering to your guarantee that you would make a 50 units profit in 1 week. After your MNF plays from Nov 23rd, you were -3 units (not counting juice) So you therefore needed to make a profit of 53 units over the remaining 6 days to reach your original goal of +50.
