Do you know who originated the projection method? The[url=http://www.thorograph.com/archive/history%20lesson.html] [u][color=blue]history lesson[/color][/u][/url] in your archives documents the early use of the 'dogmatic' statistical creation of a daily variant after correcting for the effects of weight carried, wind, and ground loss including run-up.

But I don't see much talk about using the projection of certain horse's figures to come up with a track variant that may or may not be constant for the day, due to changing track conditions, especially changes in the surface as you claim.

I seem to recall Beyer talk about it in one of his books, but I don't remember if he took credit for the idea.
