Right now, the Rachio splits watering time for each zone into small cycles of a few minutes with 30 minute pauses while the water soaks into the soil and decreases run off. That is a great feature.
However, wouldn't it make more sense to water another zone during these soaking periods? Right now my 6 zone system takes hours into the mid-morning to complete after a 4am start time. That could be greatly reduced if the system continued to water other zones in a cyclical pattern to let one soak while the next one waters.
