Graphing the Contenders

Following up on my earlier study on the BSF patterns of past Kentucky Derby fields, I graphed the prep race BSF patterns of the top 20 Derby contenders this year:
Derby contenders, BSF patterns

A caveat: Beyer speed figures are merely tools and not necessarily comparable across surfaces, and figures earned solely on turf and synthetics (such as those for Colonel John and Cowboy Cal) indicate little how those horses will perform on dirt. Still, I find the visual representation useful — it makes clear that Gayego is a real contender, that Tale of Ekati may be improving but is too slow, and suggests that both consistent Eight Belles and Cowboy Cal have more of a chance than their odds might accord.
Over on Thoroughbred Champions, Kennedy posts more in-depth work on the figures, describing six distinct patterns for Derby contenders.

wow! it’ll be interesting to see how this year’s winner compares to this study.
personally I use BSFs very sparingly but the point stands about consistency in your previous study… and again it will be interesting to see how this year’s winner compares to previous years. follows suit or pushes the envelope? will check back to find out!

This is very cool! Great idea.

I think the graph is backwards in terms of time, right? I would have the most recent speed figure appear on the right.

Yes, the graph reads from left to right, from the most recent figure back through the race before and the next.
