Soil (loamy sand) and grass type (cool season grass) are correct. Root depth is set at 6 inches.
Precipitation from a nearby weather station seems to be accurate. I don't know how to verify it though. I don't know how to look at historical precipitation data in the app.
It wants to run daily, approx. 7-12 minutes in the front and 2-6 minutes in the back yard. Front yard gets full sun and has rotor heads vs backyard gets some shade and has fixed heads.
Last summer (before Rachio) I was watering approx. every third day on my own 'smart cycle'; breaking up the watering into three segments to allow the water to soak in good. Approx 30 minutes total run time in the front and 12 minutes in the backyard.
