Hi bhagwan.

Wonder if you can do me a favour.

These are the rules to a mechanical system purchased in 1992,
was profitable for a while but then dropped off.

1= Consider only saturday metropolitan races between (1,000-1,700)

2= Consider sydney and melbourne only.

3= Target only (last start ) metropolitan winners.

4=Horses last start days between (1-14)

5= A horses last start starting price must be ($5.0 or less).

6= Starting price for todays race ($3.0-$11.0)

I added some rules when it went on the decline but eventually still lost.

The added rules were.

tab 1-2-3
20% win strike rate
3rd up > plus from a spell
Field size less than<14.

I know it will lose was just wondering nowadays how much.

cheers
