The reason that the p_max that the model is returning is different from the actual power max is because this is the fitted model parameter which represents the interception of the critical power model with the vertical axis (t=0). the "3 parameter non linear model" you are using in your second message). These efforts are then fitted to a critical power model (e.g.
The CP (and W' for that matter) are generally computed from a small number of maximal efforts. Your first error (first message) is indeed caused by the missing CP for the athlete. Great to hear that you're using this library.
