Error distributions for HF, LDA, BLYP, B3LYP, ωB97x and ωB97M-V methods over a range of k = krep = kpol values. While there are clearly some differences between the models, it should be seen that the minimum for ωB97M-V at k = 0.78 (highlighted by the grey dot-dashed line) still produces good results for the other models.
