...wherein the author quotes what was once the 'bible' for permanent magnets,
Moskowitz' Permanent Magnet Design and Application Handbook.
Last revised in 1998, the book is understandably dated.

This book, ISBN-10: 0894647687, is insanely priced at ~$200 from
Krieger Publishing which puts it out of reach of the average Joe. Even so,
it was frequently quoted and referenced, and it was with considerable
consternation that I got one in 2003.

I did it so you guys won't have to.

thats misleading- obviously you can use gauss readings as a comparison of two magnets made of the same material- the same size.
Given everything else is the same in a pickup variations is gauss level will effect inductance.
An uncharged magnet reading 0 gauss has less performance in a pickup than the same magnet reading 1200 gauss.
