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
