Error distributions for SCAN-MBE(n) calculations are qualitatively different than those computed using PBE-MBE(n), for the same set of F -(H 2 O) 15 clusters, even when the basis set and quadrature grid are the same. In particular, the PBE-MBE(n) errors have strictly alternating signs as a function of n, regardless of the choice of quadrature grid (Fig. ), which is not true for SCAN calculations using SG-2 (Fig. ). The difference lies in the fact that the PBE errors are relatively tightly clustered across the ensemble of structures that we consider, whereas SCAN errors for the same ensemble are more spread out at a given n, to the point where the errors span both sides of zero for n = 5. The SCAN errors become much more tightly clustered, and alternating signs are recovered for SCAN-MBE(n) calculations, when the SG-2 grid is replaced by the EML(75,302); see Fig. . This behavior is not unique to the SCAN functional and is seen also for ωB97X-V; see Fig. .
