The creation of the baryonic asymmetry of the universe (BAU) via leptogensis involves at least one new scale which in the traditional set-up results in an unobservable heavy neutral lepton (HNL). We investigate within the well established low-scale leptogensis model via oscillations the testability prospects of future experiments as SHiP and FCC. To this end we not only numerically solve the full non-linear set of equations to perform a bayesian analysis but also find analytical solutions within the complete parameter space, especially emphasizing the high mixing regime. We can show that for a given HNL mass splitting the parameter space generically can be categorized into three distinct regions and explicitly demonstrate analytically the maximal mixing compatible with the BAU.
