There is not another book explaning Phil's approach, but I will give it to you in a nut shell. Print a step wedge on the paper of your choice, if you are using VC or different grades paper, then print the step wedge in all of the grades.

Print a step wedge on to 5 different pieces of film. Develop the 5 pieces at different times and plot the curves. Choose the exposure index and developing times that are the same as the exposure scale of your paper.
You are done.
Read the book on the enlarger settings fpr exposing the paper and neg.
If you send me the numbers I will plot them for you and send you back the curves and analysis...
