The accuracy of pair-selected multi-level DLPNO-CCSD(T 0 ) with the target accuracy of TIGHTPNO is significantly better for the closed-shell reactions of the BH9 set compared to the WCCR10 set. The MAD only exceeds 1 kJ • mol -1 for the barrier heights of hydride transfer reactions with 1.45 kJ • mol -1 , but the corresponding SD evaluates to only 0.75 kJ • mol -1 . For the total set of reactions, the MAD is only 0.43 kJ • mol -1 for reaction energies and 0.49 kJ • mol -1 for barrier heights. In total, the multi-level variant of NORMALPNO DLPNO-CCSD(T 0 ) yields smaller MADs with 1.60 kJ • mol -1 for reaction energies and 2.08 kJ • mol -1 for barrier heights than NORMALPNO DLPNO-CCSD(T 0 ) with 1.69 kJ • mol -1 and 2.19 kJ • mol -1 , respectively.
