These Rollei filters were made from 1958, however my 1964 2.8F/ 3.5F manual does not have the CC filters instructions and all my CC filters came without the instructions sheet, but I have them in a Rollei Practical accesories booklet, it has the tables "A" and "B" that work the way you explained above. BTW, taking a photograph about a sunrise or a sunset, if you use (f.e.) a B2 filter as suggested in the tables combo you could lose part of the red and yellow colors that make interesting the scene, it could be better to increase those colors using a R5 filter; in the other hand if the landscape doesn't include sunrise or sunset, a B2 filter could work fine. The same way blue tonalities and mist for distant views could be nice and then why to use a R filter. Art and technical rules were made to be broken sometimes IMO.
