Fig. 5. ${\mathrm{\Delta }}_{\min }$ is shown between pairs of methods.

${\mathrm{\Delta }}_{\min }$ takes into account the error estimates for CCSD(T) and FN-DMC to show smallest differences with respect to these reference methods. The DFT methods have no quantified uncertainty estimates associated with them. The compared methods are: CCSD(T), FN-DMC, PBE0+MBD and PBE0+D4. The supramolecular complexes are those in the L7 data set and the C₆₀@[6]CPPA buckyball-ring complex.
