I have a question on your math.
In my opinion, what I remember from high school, the ratio 1:4 means, in this context, that for every one gallon of ro/di you make, you waste 4 gallons down the drain.
So I question you multiplying your final gallons by 4, should that not be multiplied by 5?
But I could be wrong, high school was very many years ago.

I'm multiplying by 4 and adding 1 ((D53x4) + D53), so I guess the same as multiplying by 5? It's just easier for me to visualize the 4 of waste and adding the 1 of pure water produced. D53x5 would be a simpler formula. I'm no math expert either though. Took a lot of trial & error and as you see, I had to make a correction today. I forgot to add the cell with correct formula for total throughput for the new carbon block when I created a new RODI sheet after changing the carbon filter.
