In order to find the max curvature, I am using polyfit on my data with which I can calculate the derivatives and therefor the curvature. Unfortunately it is not precise enough and so the max curvature is not right there, where it is supposed to be. I tried higher order, diff, and other fits, however I couldn't find a satisfying solution. Which bugs me quite a bit, because it seems to me like a simple task (at least i thought so). You can easily determine the point of max curvature by just looking at the plot. At the Picture you can see, that the max curvature is at around 7.5, but it should be at 11.
Maybe somebody can Point me in the right direction.
