Accuracy benchmarks in Sections 2.1.1 and Section 2.1.2 employ the S66 data set of small dimers in order to have decent statistics and good throughput on numerous variants. Where XSAPT + MBD truly shines, however, is in applications to large complexes. This was previewed in Fig. , demonstrating a MAE below 1 kcal/mol for the L7 data set, which is comparable to the best available DFT methods for noncovalent interactions, while affording an EDA that is less ambiguous, as will be iscussed in Section 3.2.
