The method offers new possibilities for testing the fitness of nuclear Hamiltonians in modeling the physics of complex $\\beta^+$/EC decays. The constraint of simultaneously reproducing the branching to $\\beta^+$ and EC transitions offers an additional constraint in tackling the problem of $g_{\\rm A}^{\\rm eff}$ determination.
