That reminds me of my days in Electronic Technician school. We had to build a circuit, and I knew the components were never as precise as the math, so there was always "slop" in the result. We were supposed to build it, as specified by the calculations, then swap out resistors, until we got it exactly right... I thought,
"Screw that! I'm not wasting that much time." I put in a variable resistor, dialed into the exact resistance specified by my equations, and then I adjusted it, until I got the perfect result. I measured the resistance of the pot, then I replaced it with a fixed resistor of that value, and called the teacher over to get signed off on it.
He complained to us, after I taught the entire class how to do it (it saved us a lot of time... and we had a lot of experiments to complete!), that he could see us all working for a company, with a vast array of variable resistors, dialing things in, to make a product.

He was just angry that we had figured out a way around his 'exercise'. A company would love that technique, as it saves time, which is money, Baby! Bike mechanics will love your technique -- they can get the job done faster, more efficiently, and more precisely! Your technique is excellent! Way to go,
Shiny!
