Just thought I would also add under $20 for each system:

System 1: ($20 and Under) :
There were 1615 selections for the System
There were 1260 which Lost (did not win race) for the System for a strike rate of 78.02%
You had to pay out $1395.12 but brought in $1534.25 after 5% commission. This means a Profit or loss of $139.13 or a percentage profit/loss of 8.61%

System 2: ($20 and Under) :
There were 956 selections for the System
There were 777 which Lost (did not win race) for the System for a strike rate of 81.28%
You had to pay out $908.23 but brought in $908.2 after 5% commission. This means a Profit or loss of $-0.0300000000001 or a percentage profit/loss of -0%

System 3: ($20 and Under) :
There were 800 selections for the System
There were 614 which Lost (did not win race) for the System for a strike rate of 76.75%
You had to pay out $681.79 but brought in $760 after 5% commission. This means a Profit or loss of $78.21 or a percentage profit/loss of 9.78%
