Boeing and ECD  have provided excellent input on this issue.  
There is another point that needs to be brought out.  Saponifiers 
work by chemical reaction with the rosin to form a water 
removable rosin soap. Unlike all the other cleaning processes 
that depend on dissolving the soil, saponification depends on 
chemically reacting with it.  Chemical reactions are a function 
of concentration of the reactants and temperature. Also, only a 
certain percentage of molecular collisions have the two molecules 
oriented correctly to give the desired reaction.  Also when the 
typical measure of saponifier (pH) drops by 1 unit, it means that 
you have only 0.1 of the previous level of saponifier, since pH 
is a log scale.  The typical way to compensate for these factors 
is to overload the system with saponifier, which can lead to 
compatibility problems.  When someone does find an accurate 
method of tracking just the active saponifier concentration, then 
this information could be fed back into a saponifier drip feed 
addition system and the belt speed, so that if the saponifier 
feed went down, the belt speed would slow to compensate for the 
reduced saponifier concentration.  So inventors- here's your 
chance!
