Query: Does GLPT2 Offer Any Actual Benefit Over Conventional HF-MP2 In the
  Context of Double-Hybrid Density Functionals?   While the inclusion of the nonlocal correlation in fifth rung "double hybrid"
functionals is definitely beneficial, one might rightfully ask whether its
evaluation in the basis of Kohn-Sham (KS) orbitals has additional value
compared to the use of Hartree-Fock reference orbitals (in a type of multilevel
scheme). We have investigated this question for a very large and chemically
diverse dataset, GMTKN55. We conclude that KS reference orbitals are
undoubtedly beneficial, but the benefit is not as large as one might
intuitively expect.
