The 123 Beyer for Frosted is at least ballpark, you can't compare generations using Beyer because of the par thing.

By the time we got to the 2004 DRF Expo Andy had realized (since I had discussed it here) why using pars doesn't work, and he said, sitting 3 feet from me, that they no longer used them. They clearly had used them historically, which is why the old figures come up so fast. And I have reason to believe they still do.

I'm shocked at the TimeFormUS thing. No race AP ever ran is close to the figure Frosted just ran. That's not about accomplishment or who is a better horse, it's best performance vs best performance.
