When we compute the MAE values for the plots in figure 1D-F per atom instead of per oxygen atom, we arrive at 0.25 eV/atom for plot D, 0.15 eV/atom for plot E, and 0.07 eV/atom for plot F. So, for this important subset of the data, the 110% PBE correction method performs better than on the broader dataset, whereas the standard method performs worse. Specifically, the MAE per atom for the 110% PBE method is reduced from 0.10 to 0.07 eV/atom (from figure to figure ), wherease the MAE per atom for the standard method is increased from 0.12 to 0.15 eV/atom (from figure to figure ). Further comparisons are plotted in the supplemental information. It is important to emphasize that the benefit of using the 110% PBE correction method instead of the standard method is the fact that it addresses the three key problems laid out in the introduction, not that it exhibits a meaningfully better mean absolute error. Addressing these problems is so important that the 110% PBE correction method would be preferable even if its mean absolute error were slightly higher; however, since it performs as well as the standard method, that tradeoff need not be analyzed.
