The example dose is not universal. Use the product label and the dose appropriate to the load and water hardness.
Fractional daily cycles represent a weekly average. Follow the product and appliance instructions.
Use total household consumption, not an assumed universal rate per person.
Estimate usage from recent purchases of the same roll size. Recalculate when sheet count or roll size changes.
