I didn’t hear the whole thing [the podcast featuring Russ Breault], so I might have missed mention of this article by Thibault Heimburger — and, you’ve probably read it already anyway, but just in case, here it is. http://shroud.com/pdfs/thibault-lg.pdf
Yes, it is excellent and I should have thought to have linked to it before. Hat tip to Jabba.
