With all due respect, and I do mean RESPECT, the people who make BRIS speed numbers are also professional people who make a living at this. And the real art in all this is one's interpretation of the numbers, from wherever they evolve or are produced. For my part and I say this in all humility, it is my interpretation of and adjustment to the BRIS figures that helps me arrive at betting decisions, not the numbers alone. On their own, they are mostly (but not completely) meaningless. You have to watch a lot of races to make adjustments that mean something. That's what I do. I'm an amateur for sure, in the best sense of the word (Latin roots) --- I love handicapping as much as anyone on this site.
I have another question for you and ask this with respect: Have you always taken horse to horse and race to race comparisons into the numbers that you make? Have you done this at the same rate over all these years? Have you been doing more of this in recent years?
I ask this because I am confused about what you did with Dreaming of Julia's last race.
