Just to be on the safe side, I decided to create a spreadsheet to keep track of the mixture amounts. I noticed something: there is actually more of components B (hydroxylamine sulfate) and C (CD-4 and Sodium Bisulfite) in the tank solution than in the replenisher solution. This makes me a little nervous that my basic math is off or that my spreadsheet is wrong…but I know film chemistry is not always intuitive. Either way, it's clear that I was using the wrong mixture.

Could one of you take a look and see if I've made a mistake?
