Experimental mirror energy differences (MED) for nuclei lying in the middle and the second part of the 1f
7/2 shell are compared with shell model calculations in the 1f
7/2 and in the full pf configuration spaces, as well as with cranked shell model calculations. MED plots are fully consistent with the description which emerges from the interpretation of SM calculations: i.e. the band-crossing of the gs band with high-K bands in A = 51 and 50 mirror pairs, as well as the seniority-3 quasi band-termination at 
in A = 49 . Rotational alignment effects are excluded, contrarily to what even recently proposed. Some inconsistencies, as well as definition improprieties, are pointed out in the topical literature.
