Here's an old one that makes millions.

Target any race with the word "Handicap" in its header race description.

Target all runners that ran 3rd or 4th Last start.

No resumers.

Bet .5% of bank on all qualifiers.

Good for 200 bets.

Divide bank by 200 at the beginning of each new day to get O/L per race for that day.

Handicap races are known for high priced horses getting up to win.
We don't need that many successes to get up to get back any losses.
