Abstract.In this one more paper on $S-$convexity, we referee, on the top of everyone else, the lower bound, proposed by S. Fitzpatrick et al, for $K^{2}_{s}$, by applying our own work to their earlier deductions. On the top of that, we define $H-H$ results also for $K^{1}_{s}$ and write a bit about why $S_{1}-$convexity is not a proper extension of the concept of convexity in what regards the set of the real numbers, but $S_{2}$ is. And, as a side result, we get to improve the range of choices for the Hermite-Hadamard inequality bounds, in terms of constants.
