Figure shows the MADs of the tested DFAs against the three sets of references for the whole test set, as well as mean MADs (MMADs) for each rung of Jacob's ladder for the metalloenzymes and organic enzymes separately. Note that the MMADs are calculated from all functional MADs including those for the plain and DFT-D4 corrected methods, not just the DFT-D3 results; plots of the MADs of all plain and D4-corrected DFAs are given in figure in the Supporting Information. Looking first at the overall results, we see that the MADs of all hybrid functionals increase as the references get more accurate, and tables S8-S10 in the Supporting Information), some clear changes in the hybrid DFA rankings based on the error ranges are observed, typically when a RE or BH that is more strongly affected by the reference values has the maximum or minimum deviation, but the impact of the references on the MDs, RMSDs and MAPDs is also minimal.
