Examining the data for neutral systems first, MAEs are very consistent (at 0.49-0.50 kcal/mol) for all of the methods except vdW-TS, but even in that case the MAE is only 0.61 kcal/mol. RMSEs range from 0.8-0.9 kcal/mol for each method. Errors are larger for the ionic species but still quite consistent amongst methods, with MAEs ranging from 1.3-1.5 kcal/mol and RMSEs ranging from 1.75 kcal/mol (vdW-TS) to 2.09 kcal/mol (MBD). Maximum errors range from 7.85 kcal/mol (XDM) to 17.20 kcal/mol (MBD). Larger errors for ions are not surprising, and the fact that the total spread of the RMSEs amongst these methods is only 0.3 kcal/mol is a remarkable measure of consistency, even if the maximum errors do span a range of about 9 kcal/mol. The mean variations between functionals are well within the intrinsic accuracy of any of them.
