Darky,

It seems your problem is fairly simple. It's the problem most typical "bet at the local TAB" punters have.

You seem to think you need to find the winner of every race you bet on.

What you need is a method that selects a group of horses with a long-term edge. Whether that method throws up 1 or 3 or 4 selections per race is irrelevant. What is relevant is whether your method provides value selections long-term.

So putting it in simple terms for you, stop looking for winners and start looking for value.
