Hello, I have a question about the water scheduling using flexible monthly with mixed zone.
Let's say I have two zones, Zone 1 is Shrubs, Zone 2 is Perennial.
When I only schedule Zone 1, the suggested watering time is 58 min. However, when I schedule Zone 1 and Zone 2 together, the suggested watering time becomes 31 min for zone 1 and 38 min for zone 2. I am confused because I don't know why the zone 1 time drops from 58 min to 31 min? I would assume the two zones should be independent.
