Miff--
1-- I explained why there are large differences between us and Ragzoin yesterday, twice. And it will be apparent if and when they post their BC figures. It is a difference in philosophy (I\'m being nice about it)-- by lumping large amounts of data together (one and two turn races, races before and after track maintenance, just to name two), and using an average, they HAVE to get different results.
2-- Beyer is getting better. Obviously they don\'t use weight, ground, or wind, and they have some circuit to circuit issues, and are not super accurate even within a day. But they are as advertised, a good general guide to how fast the horses run, and excellent value for the money. They are also MUCH better at this point at judging track speed than Ragozin. They use common sense, rather than aformentioned dogma, and never make the BIG error-- the 6 point or so mistakes I showed in those pop quizzes would be 20 point mistakes with Beyer. It doesn\'t happen.
I can\'t speak to the others, whoever they are, since I don\'t know how they make figures. If they use one track speed for the day automatically, and/or combine one and two turn races, damn right there will be differences.
3-- I\'m tired of having this conversation about the pairs, I\'ve done it maybe 50 times here. The figure relationships between horses in a race are FIXED, by beaten lengths between them, ground, and weight. I can\'t give two different horses in a race pairs of their earlier numbers unless that relationship says I can. Since THE ENTIRE BASIS of both making (and betting off) figures is that previous figures are a guide to later figures, the MORE PAIRS-- OR HORSES RUNNING FIGURES IN A TIGHT RANGE-- THE BETTER. It means your data base is tight. If I have a race where many horses run to their previous figures (whether they are tops, most recent race, or just in the range they usually run), it is the strongest evidence possible, given how figure are made to begin with, that the figures are right, both for that race and for the earlier ones.
