Just wondering what people's thoughts on this idea.

Decide on an amount for your liability lets say $100 then select 5 horses or what ever you think will lose to a maximum odds of $20 then have your staking like this.

Race 1 Price $5.00 liability $100 lay $25

Now if you win add your win amount to the liability so it would now be $125 continue this for all 5 lays adding your profits to the liability.

If you hit a winner all you lose is your initial liability plus profits, kinda an allup for lays
