Vwjyoung, all of your future smart predictions will not be based off your initial water moisture level. It is mostly based off of your location, and can be manually adjusted whenever. So if you want it starting off watering longer/more often then set the percentage at a lower amount. If you want it to not water as much or as often set it to a higher percentage. Your smart watering schedules can be adjusted for each zone under the watering schedule adjustments as well. This will allow smart watering to start off how you would like it, and adjust from there.
If you have any questions on how to set your watering schedule adjustments please let me know.
