Introduction {#sec:intro}
============

The last decade in direct cosmic-ray (CR) detection experiments has been characterized by a major improvement in the precision of the data available, and by an extension of the covered dynamical range [@AhnEtAl2009; @PanovEtAl2009; @AdrianiEtAl2014a; @Ting2013; @AdrianiEtAl2017; @AmbrosiEtAl2017]. In particular, with the AMS-02 data the community has to deal for the first time with percent level precision and a welcomed redundancy in the measurements.

But, as well known, [*great responsibility inseparably follows from great power*]{} [^1]: since theoretical predictions are very far from attaining that level of precision, both due to ignorance of the detailed underlying microphysics (CR acceleration and transport) and because of irreducible limitations (e.g. due to the intrinsic stochasticity of the sources [@Mertsch2011; @GenoliniEtAl2017a]),
