Linear regressions (Fig. ) demonstrate good correlation between SAPT+MBD dispersion energies and benchmark SAPT2+(3) values, with R 2 = 0.99 and a slope of 0.97. The ALMO-EDA2 dispersion energies do correlate with SAPT2+(3) values, using either HF or HF-PBE as the dispersionless functional, although they are systematically more attractive, and we find that HF-PBE works much better as the dispersionless functional as compared to the recommended choice of HF only. Using HF-PBE to define E ALMO-EDA2 disp , the dispersion energies extracted from PBE0+D3 exhibit a MAE of 3.6 kcal/mol (54%) as compared to SAPT2+(3) reference values, albeit with significantly more scatter (R 2 = 0.70) as compared to E SAPT+MBD disp . The primary difference between using HF or HF-PBE to compute ∆E disp'less FRZ lies in whether semilocal correlation effects are included in the dispersion energy (when HF is used), or whether they are removed (via HF-PBE). That the latter approach affords better agreement with benchmark dispersion energies suggests that semilocal correlation plays more of a role in electrostatics and Pauli repulsion than it plays in dispersion.
