Read Dick Jerardi's column in Wed. DRF. I believe Jerardi used to be one of the authors of Beyer Speed Figures (and may still be for all I know). Whether he realizes it or not, he is actually arguing against Beyer Numbers as any kind of objective standard.

More and more these numbers are being cited as fact when, by Jerardi's own admission, they are opinion. If you manipulate the numbers to fit some preconceived or arbitrary notion, you have definitely wandered into the land of opinion.

If you tell me a horse ran a 93 Beyer you haven't actually told me anything. Tell me what the teletimer said and I'll figure out for myself what adjustments need to be made.
