David-- I agree with a lot of that. It's very hard to make a determination with those that are not claiming trainers-- you don't get to see whether the horses move up when they get them or fall apart when they leave. I do remember one that moved up a lot when Pletcher got her-- the champion older mare from last year. If anyone can come up with a list of horses that moved in or out of Pletcher's barn I would be happy to post sheets.

However-- sometimes an entire barn moves forward at the same time. Happened with Frankel in Spring 01 (Aptitude's 4yo year), and roughly around the same time Pletcher's started winning everything in sight (when Left Bank went crazy, and a couple of other horses died), though I wasn't paying as much attention to him. Word was that both trainers starting using Allday then.
