The overall error in terms of MAE, MRE and MRAE for all the complexes are tabulated in Table-5. In terms of accuracy, the interaction energy of PBE-QDO is rather accurate. In electrostatic and mixed interaction type complexes, the accuracy is even surpassed than that of the the -D2 correction. Although the accuracy was decreased in dispersion complexes, mostly due to the overestimation of stacking complexes, it is still comparable to -D2. In 66 complexes, only 8 complexes show deviations from CCSD(T) energy by more than 1 kcal/mol.
