I see what you mean, but is the risk and time worth the return?

=> Bhagwan, I have been tracking the 1st 6 races system for the past couple of weeks every day. I have been tracking the 3rd fav at Morning, 10mins out, 5mins out, 1min out, 0min out and Closed and I have found 1 works better than the others. But even so it is still not returning a good profit as a couple of shocker days this week took all the winnings from last week. I am keen to find some filters to apply to increase S/R as a lot of the races are lost by the 1st fav or 5th fav getting up.

Has anyone following that system found filters such as odds, track conditions, metro vs country or the like help? Or even day of the week. I found Thurs and Sat particualarly nasty for this system.
