Let me suggest that we could all agree that his charge densities has the property that they does not radiate and possess the needed property that it can yield a discrete set of orbetals as we know the atom has.
Key of GUT-CP is the correct derivation of the magnetic energy. The non radiation condition is a missing piece of QM as the QM theory cannot explain the stability of the state(s). The non radiation condition only affects the electric energy and can be understood as a small enhancement of QM.
QM, as mentioned many times ago, completely fails to incorporate the internal magnetic energy and thus is just an engineering level theory, suitable for higher orbits calculations. QM is by no way a fundamental theory. Nevertheless for certain low energy problems it is the best approach, because the probabilities can easily interpolate dynamic behavior.
