Downloaded the Permatone mixing doc but don't understand

Hi all,

Have been using Green Galaxy WB inks for a few years, but am reaching it’s limitations. Trying out Permaset based on the killer reputation. Most of my customers come with Pantones they’d like to match, so I’m interested in the Permatone line. I’ve downloaded the mixing file, but can’t make sense of it. Anyone? Anyone?
Thanks a lot for your input.
