AMS-02 on the International Space Station has been releasing data ofunprecedented accuracy. This poses new challenges for their interpretation.In this paper, we refine the methodology to get a statistically sound determination of thecosmic-ray propagation parameters. For this purpose, weinspect the impact of nuclear cross-section uncertainties and energy correlationsin data systematic errors.
