I agree Bagman, for runners with only a few starts, the SR figures are obviously fairly meaningless as a value guide. 2yr. old races would be a good example. The same would apply to a lot of Stakes races as Mark has already shown. A common sense approach would be all that is needed to work out where and when the pricing method is useful or useless.

Your idea is handicapping the prices Bagman, although I [partially] agree and it could be taken a bit further for a mechanical approach there by separating the SR from a runner's maiden, C1 to 1MW and Handicap wins if you wanted to, but then we are really shifting into Handicapping for the purpose of selection.

I think the SR by itself is a good reflection of the horses overall ability and the trainers overall ability of selecting suitable races. If a horse is starting in the winning odds price range [say $2 - $6] that creates punter interest, the SR as a pricing guide [without breaking it down for several different classes of races], should still hold up well as a price indicator, by itself. A small break down as you suggested though, would be useful but common sense would be the best guide.

We should remember again that the method is to get an idea of SP value only and it is not meant to become part of the selection process of Handicapping, which is what a lot of readers are already or will automatically[subconsciously from well used habit] try to do and miss the point and the idea's value completely.
