Sure enough Jobst told me he learned it in Firenze, after watching a guy
steppiung on the just laced wheel to get it over-stressed, and so relieved.
What, unfortunately, the Book does not (nor could in fact) address and
answer is how safely tight a given rim can stand the tension without
eylets pinching through. This is another altogether different question
and, alas!, cause for rim failure to take notice of.
Wish rim builders did give specs about that, with whashers and eylets in
place, of course.
That would have probably saved my Nisi Mixer rims from catastrophic failure.
