Mark:

I would suggest a couple of modifications to this analysis to take into
account the reclassification. For example, if I've got my re-classes down
right, the new ES is really the old CS, so comparing 2002 ES to 2001 CS
makes more sense than comparing 2002 ES to 2001 ES. Likewise, I would
compare 2002 CS to 2001 BS, 2002 BS to 2001 AS. 

Make sense?
