@syntheticpathos I usually recommend that people start with making sure their soil settings are reasonable. If you haven’t already taken a look at the Web Soil Survey, check out this post to see if it helps.
After that, you’ll want to look at the nozzles attached to each zone, to see if they are an accurate reflection of what your system is really providing for a rate of water delivery. You can post the nozzles you use per zone, and associated precipitation rate (in/hr), and folks will chime in here to help.
