This method has many good winning days.
The idea here is price your horse to your ranking order.

1.$3.90
2.$4.70
3.$6.00
4.$7.70

The selection has to be greater than this price, just before jump

If one or more qualify , back the lot , betting the same amt. on each, level stakes.

It will always show a profit as long as you can pick the winners.


You will find the best value will come from races with 11-15 runners.
Where the Fav is paying $3.90 or more.
