The only ones I know of are the ones at the back end of the SERM and at the back end of the MacGregor books. So... you're talking about P vs. M diagrams? That makes no sense! If I had to make a guess, he's probably talking about working out your own PvsM diagram and not using the tables with the gamma x h stuff to quiz the examiner.
I will say this: the way that Alan Williams calculates columns in the SERM is the lazy way. It's fast, but will screw you over on the exams because it doesn't "display knowledge" as many put it. I will be following the PCA notes on these. PCA notes is by far the best.
