@brian, please excuse my delayed reply. Have you had a chance to check out the soil moisture adjustment feature we recently added? It allows you to recalibrate a zone’s moisture balance to completely full or empty with a click of the mouse. Your Flex schedule will adjust the next day to compensate for the adjustment.
Yes, I’d recommend doing one once a season to check your system’s efficiency. There’s a big difference between the water output and the distribution uniformity (efficiency) of said zone. The lower the distribution uniformity, the more water the system has to apply to the lawn. The meter method you used only told us how much water was used, but not how effectively.
You should be. I’d recommend logging into your soil moisture graph(s) (now available on mobile!) > select the drop down for “more detail” > then look for “Crop Evapotranspiration (-)” > this will show you how much moisture the crop is loosing from evaporation on a daily basis.
Hope this helps. Let me know if you have any other questions.
Best, Emil
