This paper goes through some major steps of a "resonance evaluator" work and in particular on actual tricky questions: the nature of the experimental data base, the life without R-matrix approximations, the external level gambling, the influence of level structures in observables other than cross sections, the puzzling unresolved resonance range and the disused average sub-threshold fission cross sections.
