I co-opted an old watering schedule to do a daily shallow watering of my garden after new plantings. I wanted specifically to water for 5 minutes daily but I forgot to turn off weather intelligence. So it watered for 6 minutes (i suppose that was the current adjustment.)
I then turned off weather intelligence to get things back to 5 minutes but the next time it watered it still went 6 minutes. Is it possible that the seasonal adjustment is not zeroed when weather intelligence is turned off?
