Variants certainly slide all over the place at Bay area tracks. The phenomenom is almost universal, however-- just greater at some places than others. Off the top of my head, I can't think of one place where the 1-2 turn relationship is fixed.

Point being, if you use our data at almost any track you will be able to take advantage of the differences between the way we do our figures and Ragozin does, and to a lesser degree the way Beyer does (he is much more flexible, but obviously does not use weight or ground, which is a big disadvantage not only in using the figures to bet, but to make fine-tuned variants). There are now gigantic differences between us and Ragozin on some circuits (as I pointed out after last years Preakness), especially those that Ragozin himself does not do (NY and Fla), but there are some real big ones in NY too, such as the ones I used for examples.
