Hi Sparker, I believe that the listings of different plans is in the CAD book (the first book), not CALP (the second book). The CAD is the basic plan, which has an Entry Version (kinda like Induction), then A,B,C, and D for after "Entry". CALP concentrates more on modifying the plan for different ages, health problems, medications, etc.. For the 4 different plans, you need to get the first book (as far as I can remember!).
