I share Martk's doubts.
Surely the point is that as gum has a clearly defined range, any fiddling
around with mixes or curves can only affect what occurs within that range. Thus
apparent increases in perceived density in the print are at the expense of loss
of gradation.
This is such a basic principle of gum printing that one is surprised that
anyone who claims to understand it would express a contrary view.
