Sorry guys I've been flat out. I'm still collating my results and I'll try and provide my findings tonight or tomorrow.
Hi Baghwan. Its no use just looking at one race meeting for this system. Of course you are going to encounter a losing run of outs. A run of eight I believe is nothing to worry about. So far I think my longest sequence is 24. However, I'm only proposing a $3000 bank for this system. So there is a reasonable amount to fall back on. This system can of course be applied to Sydney.
If you want to look at single race meetings
such as yesterday :
Sandown Race 1 no 3 at $4.50 approx
3 no 2 at $4.60
4 no 3 at $5.50
5 no 1 at $8
7 no 2 at $10
8 no 1 at $21
Additionally at Rosehill no 1 won 4 times and no 2 once.

So far I have examined 171 races
Number 1 starts 158 - winners 29 - percentage S/R 18.3%
Number 2 starts 150 - winners 22 - percentage S/R 14.7%
Number 3 starts 157 - winners 29 - percentage S/R 18.5 %

Cheers megamoos
I'm sorry I'm not being ignorant of your interest, its just very time consuming
Paddy I'm not sure where your steak knives are mate, but I'm not too cut up about it.
