Hello Torsten,

Thank you for bringing this matter to our attention. We will look into the VBA function to see if it can be updated to minimize the deviation of the orange line from the given points.

Besides, I would like to address your concern regarding interpolation methods. There are some interpolation methods that go through all the given points such as Lagrange interpolation or polynomial interpolation etc. However, interpolation method such as cubic spline interpolation does not necessarily pass through all the given data points.
