Just been playing round on an online system builder I found online. The prices and results it shows are based off highest of either official on course, NSW TAB and VIC TAB starting prices.

What I'm curious about is how much do you need to improve on say for example those horse paying $3 or less, to turn a profit either way?

I only have very limited BFSP figures to compare this against , but seems you would be break even/small loss after commission backing all these at BFSP. Someone with a BFSP may be able to correct me on this?

The results I have from the system builder are for all horses $3 (benchmark data) and under:

Selections - 17332
Winners - 3700
Strike rate - 40.66%
Ave Divi - $2.33
Loss on Turnover 5.251333%

Now lets add a simple filter over the same data period and I get:

Strike Rate - 38.9%
Ave Divi - $2.37
Loss on turnover 7.93% (2.68% greater LOT v benchmark data)

Is there enough there to crimp out a small POT (ie 1% POT) laying these?
How much is realistically required either side of the 'benchmark' figures to eek out a small profit on turnover?

I'm not interested in debating the filter added and the validity of the filter , more simply the idea of how far you need to move away from the benchmark to have a chance at making a profit either backing or laying.

Anyone care to share there experiences thoughts?
