Statistical - Cubic Regression (Cubic Spline Fit) ?

[jonmoore]

Thanks for the math lesson, Thomas. The math wasn't the problem, it's simply that I like to be a lazy bugger at times, and if there's a unicorn solution available somewhere my lazy bones would rather achieve my goal with the least amount of key presses possible.

Having said all that, I'll definitely have a dabble with your program on both the 42 and 41. Always good to have options.
