Much more abrupt changes in the rankings are seen as one goes from AVTZ to AVDZ (the right panel): M06-2x 27 is now the best, MP2 is behind LDA and beats only PBE and BLYP, and B2PLYP is now worse than all of the hybrids. Surprisingly, the performance of HF strikingly improved, and it is now in front of all semilocal functionals except for M06-L. Interestingly, GEO of HF/AVDZ is about a half of that of HF/AVQZ and a half of MP2/AVDZ. This clearly suggest that this surprisingly good geometric performance of HF/AVDZ is due to the error cancellation between the absence of correlation and a large basis set incompleteness error.
