Carl,
You got it! For the record, here are some earlier RDSS release notes re the APV and Class ratings currently showing in RDSS, along with a reference to Follow Up articles supplying the current fomulae (see Point #3 in the Changes section):
www.ArtofPace.com/pubs/RDSSUpdateNotes0.97.0.pdf
I believe that the APV/CR figs are not the strongest standalone ratings in the Methodology but can be useful in suggesting horses to focus on. For example, currently I tend to start with the 3 'colour' horses when reviewing a race, then move on to the rest.
I think BL/BL and V/DC are the critical composite adjusted ratings, but if you want ALL the horses who will finish in the top 4, consult E/L and the MU-CBL along with the Top 3 APV/CR. A good, short-term model also helps.

(P.S. not related to this thread, but the above release notes also describe the differences between Val mode and Spec mode.)
