I think that there are assumptions buried in some of your statements that do not match Rachio’s algorithm. I would recommend a) moving all but one of your zones to a fixed schedule. This will allow you to dial in one zone while the other zones are getting watered the way you want. b) Change parameters on the flex daily zone then go into your soil moisture graph and flip to the right to see how your changes affect the watering schedule. This will allow you to get a “feel” for the evapotranspiration curve and what effects will come from your changes.
