Roger:

At the end of the day, only your supplier/vendor of your saponifier can really give you the best method...

If they cannot seem to sort this out....consider this...

Titration is actually a very inadequate method for determining cleaning activity of a water based system....(I can hear the roar of screams, already, from the Technet telling me how wrong I am)... but the indicator that works better, especially in very dilute solutions, like most saponifiers are used at, is pH. 

The real problem with using pH is that there is rarely a guideline as to what pH is a good minimum set point, you are obliged to set your own. A good guideline is that the minimum should never be less than 2.0 pH units less than a fresh solution, and much safer is 1.0 pH units less than a fresh solution...although using this as a set point tends to make consumption high.

I am located about 10 miles from you (you are in Palo Alto?) and would be happy to pick up a sample of your saponifier from you, and run chemical tests and make a recommendation, if you would like.
