Hi, thanks for the quick response. I have the soil set to Silty Clay which seems to align with the Soil Survey data in you link. I didn't change the available water setting from the default which is 0.16
As for the nozzle I have Fixed Spray Head and I believe the default precip rate it suggests is 1.4. Below is a screenshot of the settings which are pretty similar for all zones except for sq footage, slope and sun exposure which can vary from zone to zone.
