I went out today and measured our zones to get watering times closer to something reasonable. That said, it seemed that the delay between cycles was much shorter than the amount of time mentioned in the article you pointed me to.
Is there a way to download the watering history into a spreadsheet? Honestly, the low contrast on your website in the watering history area makes it hard to read for older eyes. (The Color Contrast Analyzer add-in/extension for Chrome makes it very easy to see what people with mild, or severe, visual impairment - or who are just getting on in years - will see at your site.)
Thanks!
