Hey everyone want to clear this up once and for all. This behavior has been the same since flex daily schedules were released a few years ago.
If we recommend 20 minutes of watering for your zone which equates to .5 inches and you water for 20 minutes we record .5 inches.
If we recommend 20 minutes of watering for your zone which equates to .5 inches and you change the watering duration on the schedule to 10 minutes we still record .5 inches.
This was built in such a way to not modify watering frequency. We made a decision to uncouple those two things.
The only way to get back to default runtimes would just delete the previous schedule and create a new schedule.
One caveat. If you water today, then change the schedule runtime, then water again the total irrigation levels will be dramatically off since the runtime coefficient will have changed mid-day (we use this globally for your schedule on a daily basis).
If you want to adequately test how the runtime coefficient works, run a flex daily schedule, watch the irrigation total on the moisture graph, wait till next day, modify runtime, run zone, watch the irrigation total on the moisture graph. You can do those on virtual zones if you don’t want to actually water your lawn.
Hope this helps clear everything up.
