Tom to give you a bit of a start i suggest this.

Record the 1-2-3-4 Best Overall panel.
Record the 1-2 Skyform rating panel.

This will give you the best main chances till you,
Decide what race types, States, odds etc,
You want to bet on.

A lot of the time you will have 4 selections sometimes 5,
It's what and how you use them that determines profitability.

That's a start, you can progress from there as more data accumulates.

Cheers.
Gary.
