I have had 28, 25 & 23s in specialized All Condition Sport, Pro & Armadillo. All these tyres are rated 115/125. The 125 is obviously recommended max, but as for the 115 assumable min makes no sense to me. The 28 tyres, for a given weight should be able to be run at a slightly lower pressure than the 23/25s. I am currently using 25s with a front tyre pressure of 100 spi & rear 110 psi. My weight is 78 kgs These pressures are more comfortable & possibly less rolling resistance for the type of road surfaces I ride [a bit bumpy] than max pressures. BTW I notice you ride a flat bar road bike [so do I]which by all reports can be a little hard on the wrists so max pressures will jar more. I know you did not ask but while I'm "talking" I may as well add that riding flat handed with fingers resting on the brake levers also lessons jaring & fatigue.
