The original question impacts only the handicappers whose handicapping is numbers driven -- be it human or computer generated. How about people, like myself, who do not cater any human or computer-generated numbers in their handicapping? Then the answer would be: It does not matter. It's only about the presentation of basic data and which format is kinder to eyes and easier to browse.
Basic race data comes from the single source, Equibase, regardless of the product. That's the basic thing.
So if you are a 'Number Guy' (Beyer, Prime Power etc), Paulick Report published four-part series , for better or worse, to understand that basic philosophy behind these numbers, as it exists today.
