Far from being an "overcorrection", the Boys-Bernardi CP procedure is an essential aspect of non-covalent quantum chemistry that significantly reduces the finite-basis error in intermolecular interaction energies and thus showcases the true behavior of the functional in question, free of error cancellation. CP-corrected interaction energies computed using double-ζ basis sets are comparable in quality to uncorrected triple-ζ results, and therefore close to the DFT/CBS limit, even for combinatorially-optimized functionals such as ωB97X-V and ωB97M-V that are considered to be more demanding in their basisset dependence. Perhaps surprisingly, these conclusions hold also for double-hybrid functionals that contain MP2 correlation and therefore exhibit slower basis-set convergence (and also increased cost). Even for lowercost GGA and singly-hybrid functionals, the use of CP correction with double-ζ basis sets results in computational savings, as this approach is 3-4× faster than computing CP-corrected triple-ζ interaction energies, and somewhat faster (1.2-1.6×) than computing triple-ζ interaction energies with no CP correction.
