New Thoro-Graph record?

[Thunder Gulch]

Brown makes a compelling argument on horses getting faster based on the cushion on the tracks getting deeper through the years. At the end of the day, it is really difficult to believe today's classified allowance horses are faster than Secretariat and Bid, but it's an interesting look at some of the more sophisticated factors the TG guys use. I think there is some evidence and the breeding of today probably supports Brown's theory that brilliance is taking over where stamina was just as important 40 years ago.

I guess it really doesn't matter for handicapping purposes because we're only talking about speeds relative to the current competition.
