I wonder how they are calculated? Obviously it is more than just a computer ratings program as they rate horses having their first start. As an example yesterday, Ballarat R2 # 4 PRIVATELY. Top in the Pre-post and the fixed odds market had it around $1.40 as well.

It appears they have some inside knowledge! Maybe its barrier trials?

At the time they calculate the Pre-Post I would not have through sufficient money would have been invested to make that judgement as in this case we are talking about a maiden in Ballarat!

As we cannot rate those horses, we bypass any race which has a horse having its 1st start; but maybe we are missing something.

Any thoughts? ... Fred
