By reviewing my own work, which is based on the figures the two of you gleaned from your careful observations/measuring (from the table taken from Kerri's book), I came across a very interesting confirmation of your work.
I wasn't there when you conducted your experiments and made/documented your measurements, so how can I know they are correct, how can I have faith in them? I'm not being sarcastic, I know they are correct. View the attachment: you can see two sets of numbers; the first set is to make CDH with 35% Citric Acid and the second set is to make CDH with 50% Citric Acid. The only difference between the two sets of numbers, IN THE CDH SECTION, is due my selection in Excel where I put in the number of decimal places to 2, otherwise the numbers precisely match each other.
What am I getting at? How do I know your work was correct/precise? To make any amount of CDH, there can only be one set of numbers, no matter how the components are broken down, which can be true to make CDH at a correct concentration (ppm); and no matter if I calculate based upon your figures of Citric Acid 35% or Citric Acid 50% the numbers come out the same!
THANKS FOR YOUR WORK!
