It is funny you mention my friend Sheldon, I was talking with him on the phone about some of these subjects 6 days before he died. He was sick for a long time, but he did not know he was going to die that soon. He loved his opinions on all types of bike subjects, and was surprized by the science and six sigma continuous improvement process that was happening in bike education.

It reminded me of ShelBroCo April Fool's pages.

Thanks for that Nicholas. Christopher's original post disturbed me, but as I am a relative newbie, I did not want to call him out. You did the right thing, in a very respectful fashion.
Warmly Dennis

In other words, it's obvious that while some spokes may become loose through repetitive stress, since the web of spokes share a single load, others will become tighter as the rim deforms. Since little can be done in the average shop to re-perfect the bare rim once deformed, the tighter spokes must maintain some amount of increased tension to keep this now-deformed rim true.
I'm not going to present any test that I've developed to "prove" this process, I'm actually posting this response because I find it kind of offensive that you keep posting here essentially as a salesperson. When someone posts to a mailing list to sell a product, to me that constitutes cause to block that person from the mailing list.
If you want to freely share here tutorials and techniques for everyone to review and learn from, in the interest of helping community bike shops hone their skillsets to a higher standard, I'd be the first to get interested. As it is, you never post detailed instructions, and quite frankly a lot of the processes you allude to are bizarrely out of scope with what most of us do on a daily basis. Your posts smell like bait.
I'm personally requesting that you reconsider posting here. In this particular case, you even tacked your message onto a completely unrelated thread. I mean, might be I'm actually talking to a spam bot.

I will ask a few questions and I am seeking if you have tests to prove your answers.
Does a quick release lever change the adjustment of a hub? Yes or No is not important, how do you test to verify your answer is important. How can this test be used to reduce service time to 1/20 the time?
What does facing do for the customers ride experience? Nothing/ Something? The following answers are guesses, beliefs, not science or engineering based: it should be done, it is done at the factory, it does not need to be done, eliminates pedal click, professional cyclist have it done. So what does it do? how does it improve a cyclist ride experience? How do you verify your answer?
How do stainless steel spokes and cables stretch once and then magically become harder and never stretch again? If they do not stretch once, then how do they get longer once? How do you verify your answer?
Do Bolts stretch? Yes or No, how do you verify your answer?
How does a chain that can stretch at 900 Kg or 2000 pounds of force get stretched on a bike frame that can only support a 160 Kg or 350 lbs cyclist. How can a 45 Kg or 100 pound cyclist put 900 Kg or 2000 Lbs of force into a chain to stretch it? Without destroying their knees? How do you verify your answer? Which leads to the question, How does one type of shift lever make a chain function twice as long as another type. How do you verify your answer?
Why do mechanics tighten and loosen spokes? When a cyclist uses a wheel spokes get looser. Spokes only need to be tightened to round, dish, tension, and true a wheel. How can finite element analysis and computational fluid dynamics help a mechanic work 36 times more efficiently?
How can understanding the Sphere Stacking Equation improve the hydraulic systems on a bicycle? (Both hydraulic braking and suspension systems) and make cycling safer.
How can a mechanic use a bench as a tool to reduce service time 25%
Would it help your school, your students, bicycle businesses and cyclist; if your curriculum included verifiable testing processes, efficient practices to reduce procedure time 25% to 50%, service sale language to help cyclist understand what a procedure does to improve their cycling experience to improve sales?
If any of this or all of this is new to you and you would like to improve your training, feel free to reach out and start a conversation telephone only. 773 -490 -0683 Christopher O. Wallace . I am located in Chicago Illinois.
PS Yes I have re-invented the wheel three different ways, I am looking to improve the cycling industry and I feel schools are the best way to do that! I look forward to hearing from you.
Sincerely Christopher O, Wallace
