How to use this result
What it means
The gallons answer shows the weekly deficit after rainfall and delivery efficiency.
Next action
Split runtime into one or two deep sessions unless heat, containers, or sandy soil require shorter cycles.
Check these before using the number
Counting rainfall without checking depth
Light rain can wet leaves and mulch without refilling the root zone.
Convert inches into a real watering session
Bed size, rainfall, delivery efficiency, and flow rate decide what a weekly water target means.
If a plant keeps wilting after the numbers look right, inspect drainage and roots before increasing frequency.
