Hi CRASH.
It works well for me.
The maximum I would outlay to win $100 would be around the $70 mark ( with 4 - 5 horses )but most times considerably less.

For myself I am definitely NOT in favor of betting 1 horse a race as I believe there is ALWAYS a danger ( or 3 ) and this way suits me admirably.

Today I would be betting the Ballarat Cup ( winnerinsix) at Daves rated prices.

Cheers.
