TG--1. You weren’t wrong—given the data you were using, you came to exactly the right conclusion. That’s the point.
2. Its not about bonus points. She won by open lengths at the routes—she only “clearly enjoys sprinting” if you believe the Ragozin numbers. The question is whether it’s REASONABLE to believe she won those races running total X’s, since the others behind her ran worse.
3. 6 points = less than 2% difference in final time. Are you saying that a turf course that was soaked with rain earlier can’t have gotten 2% faster as it dried over a couple of hours? Incidentally, the grass actually got less than 4 points faster.
4. I answered this on your other post. Call me next time, and we’ll bet.
5. Uh, David—they don’t all look good on TG. In the Derby, I took a stand by throwing out the favorites—one of whom was Friedman’s pick—and crushed the race.
What is true is that the horses run in a tighter range, and if you knew more about making figures you would know what this means. All those horses on Preakness day are coming from all over the place—different races, different tracks, different distances. That Quixotes Hope gets a sprint number at Pim that ties in with her route numbers at Pha confirms both figures, etc., etc. You can’t make a whole race fit (give lots of horses figures in the range they usually run) unless either:
a. you screw around WITHIN a race, adjusting the relationship between horses dramatically (which the Ragozin office would have pointed out long ago—while we use greatly different approaches to variants, our formulas within the race are similar). We don’t.
OR
b. the figures are accurate—both the ones you make, and the ones you use to make them.
6. We charge less in order to expand the market, and boy, is it working (this is the same theory Ragozin uses in charging horsemen less than 10% of what we do, despite which they have only had a tiny fraction of the success). LOTS of top bettors have migrated over here.
7. I didn’t “pull a handful of races from one card”. Friedman almost never posts a whole card—when he does, like the Breeders’ Cup, and there are differences (errors), I post a response.
