BrowserUk,
I think I understand now. The financial stuff you were talking about was probably some form of regression analysis using the least squares method. I don't think that would work for your problem because your lines curve back under themselves though you might treat them as a few lines and have it work.

My apologies for not providing anything more concrete but a post to one of the math related reddits may provide insight (/r/math, /r/learnmath, /r/matheducation, /r/EngineeringStudents, /r/AskEngineers

You're probably right -- certainly about attempting to line fit -- but another bulb in my brain makes me think of Lissajous curve; whereby the formulae for sin() and cos() are combined to produce curves that loop back on themselves; often many times depending upon the frequency differential.
