For ^1S and ^3S Rydberg series of helium, it is successfully attempted to improve Smith's Hartree-Fock type variational calculation of the asymptotic values of quantum defect,Δ_∞, by adding only a few configurational wavefunctions of analytic form to the primary Hartree-Fock type one. The best values of non-linear parameters in the added configurational wavefunctions are chosen on the basis of the minimum principle for Δ_∞, which is here rederived straightforwardly from a well-known theorem on Rayleigh-Ritz's variational treatment. The integer parts of Δ_∞'s, that have been left indefinite in all the calculations by predecessors, are determined pure-theoretically with the help of another inequality relation which is also a direct consequence of the same theorem.
