This seems to jag a number of winners.

Target at all runners <=$10

Ignore Fav

Target those runners where the FAR price is half of NEAR price.

Back at current price
Lay at $1.00 -1.50 of Back price & keep in-running.

Betting same amount on each.

There can be 1-3 qualifiers , bet them all.


4 min or less till jump.

Example
Back 10.00 at 6.00
Lay 10.00 at 5.00 or less. Keep in-running.
Diff 1.00
1.00 x 10.00 = Prof +10.00 if it wins.
If it loses - Break even, free bet

What often happens is that they shorten in running & a number get up & win.
If they get matched & fall over , we break even, thus a free bet.
