Turning off weather intellegnece

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?

Correct. We will be revisiting fixed schedules (weather intelligence, budgeting, etc.) and giving it an overhaul for next watering season.
