I've had a couple of exchanges on the forum over the last three years on the Roushayd example, and posters have identified why they disagreee VDW's conclusion that he showed improvement on his last run before the 1988 Old Newton Cup and judgement that he was a certainty in the race. The points raised are, from their point of view, perfectly valid. But from my point of view as someone trying more fully to understand VDW's approach they are irrelevant.
It is the same with Buckbe. One can perfectly reasonably have different views about Buckbe's performances, including runs before the 3rd last before 27/12/84 and one might reach different conclusions than VDW did. But from the perspective of trying to understand his approach more fully, we simply need to take his comments re Buckbe's class/form status not being consistent as givens and work out why. With ability, we use all a horse's last wins, however long ago. But for "form" and issues such as what constitutes class/form status and consistency, all the evidence suggests that VDW considered just the thre most recent races. From that perspective only one was a "form" run as I understand it, and explains the "form" part of class/form. I think that the other two were not "form" runs explains the not consistent comment.
