Question for you old timers!

[DaveDuggan]

Hi, I\'m trying to find out how speed ratings changed american horse racing; and I thought, who would be better to ask than you guys that actually changed it, or at least remember how it was before (Yeah you\'re old!).

Did the overall betting volume increase after the Beyer(etc) became public stuff? Was it any trends/stories you think might be interesting given my approach here? Did it change anything?

And if you know of any documentation/articles on the topic, that would be great! But of course, I take your word for it as well!

Cheers guys, would be much appreciated!
