Hi xptdriver,

My ratings are basically calculated on overall class and last start performance.
I do not look at rating a horse on it's best run, as that can be long ago and have no relevance to today. The one thing that is not factored in, is a long break or first-up into the equation. He is basically thrown in as a first four chance, I think the other first three rated horses are lengths ahead - but you never really know.
