Good to hear this will be added. We have a CyberRain system now and take extensive advantage of this. Some of our beds along the house spill over to the driveway in very short time. We run 2 minute max on these and up to 30 minutes total. Once the soil gets a little moist, it takes the next water a little better. But we have found numerous short cycles really works a whole lot better. We have about 10 cycles on each of 8 zones with about 3-4 minutes for most cycles.
Since some zones require less time (sprays are faster than wide-area rotarys) the time between zones starts to got short as fewer and fewer zones remain in the rotation. This is where the minimum soak time comes in. We use a minimum soak time of 10-20 minutes, so there can be fairly long periods of time when there is no watering going on at all.
For our lawn with lots of clay in the soil, this really is an important feature.
