Thanks for the comments. It appears I'll be pushing uphill to get a result in my favour.

However, I will persevere and see how far the trek takes me!

Strategy is to take the opening price as the divisor into amount required to get $'s bet. I would think 9 times out of 10 the final dividend will be greater than the opening price (no figures just my gut feel). This is where I will have built in an advantage.

Time will tell.

I am also looking at Victorian Country meetings (from 1st January).

1st fav...45 bets...bank $38.30
2nd fav...45 bets...bank $43.60
3rd fav...44 bets...bank $39.50

The chase is on!
