Thanks.
Will start with setting root depth to 6" (from 4"). I also filled the zones again.
The coefficient is set to 80% - I would not have changed that setting from the default. I only recall changing the soil type and have reset that to loam per Franz recommendation in this thread.
Currently, within the zones, it indicates a watering on Friday morning, four days after the watering of zones 3 and 4 and six days after 1" of rain.
