I am adding a 4th System which I will monitor.

System 4:
There were 464 selections for the System
There were 330 which Lost (did not win race) for the System for a strike rate of 71.12%
You had to pay out $383.94 but brought in $440.8 after 5% commission. This means a Profit or loss of $56.86 or a percentage profit/loss of 12.25%
