The variables are just that - variables in the equations, to be measured and plugged in. I set up a spreadsheet for my own edification, using the readily available string scaling formulas. I figure that if these formulas can give you a close enough approximation of tension and elongation from diameter, length, and pitch, they can be rearranged to produce a close enough approximation of pitch change from the other direction with an elongation length change. Why the interest? it's called education. I like to be able to generate "good enough" answers, whenever possible, to my own wonderings. Ron N
