In Bi2212 and La214, the low-T (T [much lt] [Tc]) superconducting gap magnitude 2[Delta][sub 0] and the temperature dependence of in-plane resistivity [rho] were examined over a wide carrier-doping range. In both systems, 2[Delta][sub 0] increases with lowering doping level and [rho] starts decreasing faster around a temperature T[sup *], comparable to the mean-field [Tc] or the onset temperature of a spin-channel singlet formation in the mean-field RVB theory, each of which is given by [approximately][Delta][sub 0]/2[kappa][sub B].
