    We believe that any adjustment and updating process (AUP) should try to minimize the relative deviation of the new coefficients from the initial ones in a homogeneous way. This homogeneity would mean that the magnitude of this relative deviation is similar among the elements of each row or column, therefore avoiding the concentration of the changes in particular cells of the SAM.In this work, we propose some new adjustment criteria in order to obtain a homogeneous relative adjustment of the structural coefficients. We also test the usefulness of this proposal by comparing its results with the ones obtained by more standard approaches.
