We elaborate on several topics related to the adjustment formalism, of which LEPRICON is a particular application. The latter is a most reliable way for estimating the fluence in pressure vessels of reactors from given iron cross-section data and surveillance-dosimetry measurements. New insights of adjustment should hopefully also enhance a deeper understanding of dosimetry. Our review includes the following: (a) Adjustment for pedestrians — an even more elementary derivation of the comprehensive prescriptions, based on geometric considerations in the parameter space and on arguments relating to dimensions of vectors and matrices; (b) the iteration of adjustment, is it worth its while? and (c) absolute and relative uncertainties and sensitivities.
