I don't understand something. In your first day, you say to play 90 numbers @ .50, which would equal $45.00. Here in Florida, and in all states that are not parimutuel, the winning payout for a .50 bet is $40 dollars, not $75. I would be $5.00 in the hole.
How do you come up with $75.00?
The same goes for day 2 and day 3. I don't know where your getting those high payouts from.
