"The amount of solvent action in developers depends on much more than the concentration of sulfite."
interesting but how does it exactly bear upon the topic? the op wants to know if 75gr is going to improve sharpness over 100gr. in a developer consisting of water, sodium sulfite and metol i'm struggling to see where else the solvent action is going to come from esp. when it is the classic parameter to modify when one wants solvent action and the lack of grain associated with it.
