The Ultimate Odds Line
This is really good work!
Do you recall how Huey Mahl did this thing he called
The Length Variant? This connects me to the next idea, and all of it connects back to YOUR WORK.
When I was doing work for some AUS a couple of years ago, I found some of their ideas quite intriguing. One was the idea of expressing "How They Ran" in terms of Odds & Beaten Lengths.
Thus, if you look at each odds range, and come up with the average lengths behind, one could say that a horse who ran (say) 2.5 lengths behind ran like he was (say) 5/2.
Your work is similar but expressed as a win percentage (I assume).
This is a really goods idea.
