He also finds the "back-off the spoke" procedure inefficient (not my experience at all, even with 130Kgf spoke tension on Campagnolo hubs), so instead of avoiding spoke wind-up when building the wheel, he actually suggests some cumbersome ritual of side loading the wheel afterward to release the probably wast amount of spoke wind-up, which of course will result in instantly wobbling the wheel so it needs truing again. The spoke wind-up also nullifies the cumbersome spoke tensiometer calculation that is suggested earlier in the chapter.
I think that the major difference between Jobst Brandt's book and this chapter is, that Jobst Brandt is a engineer and pioneer in the scientific description of how wheels function and therefore knows what he is talking about, while the guy who wrote the Barnett chapter doesn't have any engineering background at all.

I certainly agree that the Barnett Bicycle Institute chapter isn't perfect or laying out engineering principles.
However, the section of Barnett Chapter 17 "Stabilizing the True" gets to a method that Rolf modified and is most successful for the builds I do in getting the spokes "bedded in" such that the wheels I build stay true (stabilized) better than the spoke squeezing method that Jobst says relieves stress.
Misinterpretation happens a lot. Barnett's author, you, and I do it. Attributing cause and effect are also pitfalls.
I find the illustrations in Jobst's book (at least in the 3rd Edition) and his at least one of his graphs to be totally misleading/incorrect and his method of determining spoke tension to be hazardous to rim life. I have also never been satisfied with Jobst's explanation of "Stress Relief".
I will read Roger Musson's eBook some time and see what his approach is. I certainly understand that there are things I can still learn after building more than 1,000 wheels. I think Roger's money back 100% no-risk guarantee will get me reading it sooner than later.
