New action
Skip watering when the soil is wet enough
Adjusting irrigation to soil moisture and weather can avoid unnecessary watering.
Your scenario, drawn
Skip only unnecessary cycles
One symbol = 1 unnecessary irrigation cycle skipped in the year. Count only cycles genuinely avoided.
Water volume only. Water heating and water-supply emissions are excluded.

What changes the result +
EPA WaterSense describes controllers that prevent irrigation when moisture is sufficient. Check root-zone moisture and plant needs; rain alone does not establish that watering is unnecessary. Count only cycles genuinely skipped without later compensating water. No controller purchase is assumed.
Before the next scheduled watering, check moisture near the roots and the forecast. Skip the cycle only if the plants already have enough water.
