  We analyse the full counting statistics (FCS) of a superconducting junction
in non-equilibrium in the limit of small interface transparency. In this limit
we treat both supercurrent and multiple Andreev reflections on equal footing
and show how to generalise previous results for both phenomena. Furthermore, we
also allow for different gaps of both superconductors and investigate the
intermediate regime which allows to make contact with previous results on
normal-superconductor heterostructures. We also compare our predictions in this
regime to experimental data.
