@chris You were right. I was adjusting Available Water directly in advance settings. I did this based on data from the Web Soil Survey detailed in this post and promoted in the original post of this community thread. I also chose loamy sand based on the same data and nozzle in/hr based on specs from the Hunter website.
In addition I chose to water only 2x per week (M,F) for right now (instead of my allowed 3x/wk - MWF) based on recommendations form local landscapers. I will increase the frequency to 3x/wk likely in July.
