Registered just to say thank you @azdavidr for putting this together. I’ve struggled with emitters for a long time and finally just decided to dig in and really calculate these numbers using the spreadsheet, and everything looks great. The only thing I noticed different with my Rachio 3 is that you don’t create a custom nozzle, you just set the in/h measurement in the advanced settings for the zone.
Also I had the same problem as @BiebsAZ in that my flex daily showed 0’s, but then I realized I needed to create my flex daily schedule and then let it run at least once and then the numbers showed up. All minor things though. Thanks again!
