Hi Gumboot and Crash.
I agree .Too many variables and you exclude most horses.
For me I prefer to look at a couple of standouts in a 1200-1600 race in a smaller field.
That seems to work best for me.
Today for example there appears to be 1 race with 2 top chances .
I couldnt imagine myself betting 25 -30 horses a week but thats just me.Everyone to their own I guess.
Cheers.
Darky.
