Thanks for your comments indicating that this mathematical exercise has some real utility for you.

So often, folks are completely put off by anything that even hints of math, that its utility is overlooked as they flee. Showing them that there are applications out there where it can help will encourage them to look a bit closer at the next offering.

Well said, too often, in schools, random generic formulas ... with no practical application, confuses and frustrates otherwise willing learners. Same on the shopfloor. Often an example gives what otherwise seems like Egyptian hieroglyphs a plausible and useful application. I've had young students who said "I don't need school" change their mind when they actually saw how to apply a mathematical concept in real life. It makes all the difference in the world for many.
