It appears that one cannot adjust the amount of refill done by a flex daily schedule, with it always attempting to do a 100% refill. Even after reducing the scheduled irrigation times for each zone, it still shows it trying to do a 100% refill. Is that because it’s imposing the rule that one should water deeply, and less often?
A counter case is in an area where most water comes from rain, and minimal irrigation is only used to prevent wilting. In this case it makes more sense to match the evapotranspiration rate than to do a 100% refill. Another case is where one has limited flow available, and it is impractical to do a 100% refill in a single day. These cases could be supported if we were allowed to set a refill percent (or specify refill inches or times).
