. Application of this procedure to the S22 data set, however, leads to ALMO-EDA2 dispersion energies that are systematically and dramatically more attractive than SAPT2+(3) values, as documented in Fig. . In our view, these sizable discrepancies arise because the recipe in Eq. ( ) assumes that every correlation effect is dispersion, when the "dispersionless" functional is selected to be HF exchange (only). Therefore, we experimented with using HF exchange plus PBE correlation (the HF-PBE functional) as the "dispersionless" functional in Eq. ( ). This affords dispersion energies that are much closer to SAPT2+(3) values, as shown also in Fig. , even while E ALMO-EDA disp remains systematically larger than E SAPT2+(3) disp for the dispersiondominated and mixed-influence subsets of S22, for which the contribution from electrostatics is smaller.
