The conclusion and/or appreciation of this 3 tools work sheet is left for philosophy. Use the one of your preference. The "Gaussian like" model is intentional in reference to such curves appearing daily in statistics. Some collab might have the patience to investigate about other common shapes. The interesting point is the traceability of the methods proposed, but the point here is about methods 2 and 3 and their originality, i.e: do they have a name or reference to known materials ???
Please: enjoy and comment as needed.
