I am completely puzzled and need help. I originally created one schedule for my three zones (grass and two drip zones) using flex monthly. Based on my zone configurations, it recommended the following durations which seemed reasonable based on prior watering:
Front Yard (drip): 32 minutes
Back Yard (drip): 47 minutes
Grass (fixed spray): 16 minutes
I am now separating my drip zones into a second schedule. As a first step, I created a schedule that is exactly the same as my original schedule, only change is I removed the grass zone. With no changes to zone configuration or anything else, the durations changed drastically in the new schedule:
Front Yard (drip): 2 hours 29 minutes
Back Yard (drip): 3 hours 43 minutes
And then it gets even more strange - if I remove the front yard drip zone from the new schedule, the back yard drip duration changes:
Back Yard (drip): 4 hours 4 minutes
So for identical zone configurations, I have three different suggestions for my back yard drip zone - 47 minutes, 3 hours 43 minutes, and 4 hours 4 minutes. And my front yard drip zone is either 32 minutes or 2 hours 29 minutes, depending on which of the other two zones are included in the same exact schedule.
Can someone explain this? Thank you!
