The heartbreak of linear-ness

Today lots of progress was made. As previously discussed, we did manage to get our hands on a frequency measurer which allowed us to get to testing. We used a standard acoustic guitar and measured the frequency of the low E string for each fret. Comparing the frequency with the length from the fret to the top bracers, we obtained data that appeared to be frighteningly linear. Not all has gone to waste thus far however. We plan to keep the experiment very similar with one small change. Rather than using length as our independent variable, we will vary the tension off the string in hopes of non-linear results! We're in the process of bouncing ideas off each other of a way to accurately measure the tension in a fairly feasible way.
