@don Be sure to double check your nozzles for each zone. Given the same root depth & soil parameters, the nozzle will make for a different run time for a given zone. Based on your screen shot for 'Front strip and South center' the run time seems to match what you have for settings. Also go to one of your scheduled watering days for the lawn zones and if the 'Smart Cycle' is on, you might see it say 'Cycle' & 'Soak'. Given that you have Clay there might be breaks of 30 minutes or so during the watering to ensure that the water has time to soak into the soil. The 13hr appears to be a total for all of these. At the beginning you might see them all run the 1st day, but eventually some of your zones might drift to days separate from each other.
If you have anything that uses drip or emitters, move them to a separate schedule or the cycle-soak won't engage for those lawn zones.
