Um,

You're still talking about a retrospective model. However, the spreadsheet does account for the before/after differences. Not quite sure what you are getting at.

Relax,, I'm on board with that which you have submitted.
Only disagree with your statement that TDS meters and or test kits cannot measure the effects of proper maint and water changes or a lack thereof ,,on Total dissolved solids,Total suspended solids,and or conductivity of a sample of water.
Been using such tools for a few decades
Everything that enters the glass box of water that we throw money, and or products into ,,from fish, fish waste,water conditioners,carbon, chemical media,buffers,fish foods,fertilizers,salts,medications,along with source water, contributes to Total dissolved solids or conductivity and or Total suspended solids, or at least that is my view.
Can easily measure the (effects )of water changes and maint schedule ,or a lack thereof ,,, on reducing the levels of TDS ,or conductivity recorded ,,with the tools mentioned. Just need a notebook and a pen.

My point exactly: such things can be measured (at least indirectly), but only after the change takes place. That is what I am saying; I am saying that it is good to examine methods that do not rely on after-effects. :)

Agreed. Limiting that which goes into the aquarium is good preventitive measure ,and a measure I fully endorse as well as practice.
My apologies If I appeared unable to grasp your meaning. I am old.

No worries. I know that you have a good head on your shoulders. I, on the other hand, have the tendency to bounce to absurd extremes. :)
