Actually, Beyer has told people that Secretariat's Belmont turned up like a 153 Beyer speed figure or something crazy like that in their first few calculatings of it based on their formula - but then they adjusted it because they weren't going to give that much credit when they didn't have all of the proper variables at the time to better measure his performance....I don't know how they determined he ran about a 139 instead of a 153....that would be interesting to find out...must have thought that it was impossible...

I have also heard that there have been at least one or two performances that he thought was quantifiably better than THAT, believe it or not.....I know that he said that one of Dr. ***er's races would have scored out in the 150 Beyer Speed figure range......WOW!
