Overall, good agreement between the two F12 methods and the DF-MP2/aug-cc-pVQZ is seen, and again DF-MP2/aug-cc-pVDZ seems to be quite off. Here it actually seems that DF-MP2-F12/cc-pVDZ-F12 would be the optimal choice for accuracy, but the difference between this and DF-MP2-F12/cc-pVTZ-F12 and DF-MP2/aug-cc-pVQZ is so small that we attribute this to a lucky cancellation of errors.
