As for the WCCR10 set, errors of NORMALPNO DLPNO-CCSD(T 0 ) are partially compensated by errors of the pair-selected multi-level extension. However, regarding the results of the separate subsets, this only holds true for reaction energies and barrier heights of pericyclic reactions as well as for reaction energies of hydride transfer reactions. NORMALPNO DLPNO-CCSD(T 0 ) provides more accurate results for proton transfer reactions, nucleophilic substitutions, and nucleophilic additions. For instance, the multi-level extension increases the MAD for nucleophilic substitutions from 0.79 kJ • mol -1 to 0.83 kJ • mol -1 for reaction energies and from 2.07 kJ • mol -1 to 2.67 kJ • mol -1 for barrier heights. But due to the large number of pericyclic reactions, the results of the total set of reactions are dominated by this subset.
