Thank you for your interest. You are right in the sense that the curve fittings in my file seem to be equivalent to the ones already available in Excel. However, the advantage is that all the fittings are done simultaneously and the best curve is visually indicated via an hand. Also, it includes the hyperbolic curve fitting, which is not available in Excel. In addition, the file is bilingual and formatted for printing and where the only writing required is the entering of the data and the subject of the curve fitting.

Thanks for the upload. Maybe because I don't fully understand the purpose of your calculation could you tell me how your power curves are different to native Excel functions featured here.
