I don't think the above is an accurate statement. To my knowledge the Rag method was to assume the track "variant" was a constant for the day unless there was a climatic event. Thats tying races together. TGraph on the other hand is on the advant garde regarding track speeds changing throughout the day. We know they do. All you have to do is consider the drying out track at Lone Star Park on Breeders Cup Day. If I understand it correctly TGraph uses the Rag method when the track produces race times for the day consisent with the track remaining uniform. When the track changes TGraph factors the changing track speed. Clearly there is some art to that. To my mind its art to counter bad "science".

But let me ask you this: "Whose number is going to be more credible in this dilemma, the concern that scrutinizes and discusses their methodology or the concern that allows errors to go uncorrected and discourages debate?"
