@redwagon If you use the 1 sq. ft. assumption, do a sanity check on your run times once you use the associated PR. I found the watering duration to be vastly lower than what it should be using the 1 sq. ft. assumption for single point emitters. I know the 1 sq. ft. assumptions work for some. Maybe it’s due to desert watering requirements, but I would check your watering times against what you expect them to be. My PR for my 2 GPH drips (3 per tree) is 0.4 in/hr to get the deep watering we require. At 3.3 in/hr my run times would be 8 times shorter than the local (Arizona) recommendation for my trees.
