Yes, the restricted days are mandatory and I realize it severely limits the function of Flex but I'm curious about how fixed with Weather Intelligence is any better.
The system still only waters enough per day to fill up the available capacity, right? And doing that twice a week is still not enough to keep up with ET, right?
Unless Fixed + Weather Intelligence is just figuring out what the needed watering is and dividing it by the number of non-restricted days but that would mean it's ignoring capacity and potentially overwatering.
Either that or it's just doing it's thing but only doing it on non-restricted days in which case it's not getting watered enough exactly the same as Flex.
