@plainsane I have it set to the default ‘Fixed Spray Head’, which says 1.5in/hr in the app. I changed my area to 510sf, but maybe I shouldn’t have ? I have 510sf for the whole lawn, with maybe 6 or so sprinklers covering that area. Warm Season Grass, Sandy Loam, Lots of Sun, Fixed Spray Head, Steep, Area=510sf, Available Water 0.12in (default), 6in RD, MAD 50%, Efficiency 80%, CC 65%.
The cycle is 9min duration, 30min soak, 9min duration.
