*Only* 13 horses in the top 24 order of entry are actually within the top scoring levels in walkermac's table (i.e. scoring 10, 9 or 8). Obviously things can change a bit but if you want to be really strict and only look at horses within those scoring levels it helps eliminate half the field which is quite handy.

On top of that if you eliminate a few runners based on how they are weighted vs their rating and/or appear to be a little overbet then you can narrow things down quite a bit. For example if you look at the current Melb Cup futures a lot of the Caulfield Cup placegettors have had their prices brought right in. In addition Constantinople is now the clear fave when it has some solid hurdles infront of it in terms of weight vs rating which walkermac has highlighted.

I find myself looking more at Vow and Declare and Mirage Dancer after the caulfield cup.
