With the exception of the ill-behaved aug-cc-pVDZ, errors in the extrapolated interaction energies are consistent across basis sets, differing by no more than 0.02 kcal/mol across basis-set cardinalities. At least for these small dimers, this implies that double-ζ basis sets provide a representative assessment of the accuracy of the DLPNO approximation. That said, the outliers noted in Section III A for aug-cc-pVDZ lead to extrapolated results that are less accurate in that case. In this particular basis set, there is no guarantee that an extrapolation using tighter PNO thresholds will be more accurate than results obtained using looser thresholds.
