Anyone still believe in 'em?

Anybody who has read Ralph Morrison's "Grounding and Shielding Techniques in Instrumentation" - ISBN 0-47124518-6 - knows that they work. and how they work.
The ISBN is for the fourth edition, which is what I've got on my book-shelf. I read the first edition when I was a graduate student, and got my employers to buy later editions for the edification of junior engineers.
You need to know about stray capacitance, and how to calculate rough values for it, to grasp the value of guard traces, but once you have got that far it's all evidence-based understanding, rather than any kind of optional belief, or one of Cursitor Doom's demented conspiracy theories.
