One thing I do like about the new As Needed schedules is that multiple zones can be tied together in some way. That way, if I do a bit of manual watering, it doesn’t throw two adjacent zones off like on Flex.
It seems like it is best for zones that have overlapping sprinkler heads to run on the same days so the half-waterings that the between-zones area add up to a full deep watering and don’t ever get split onto separate days (resulting in two half-deep waterings on different days).
I know tying together very different zones is problematic, but similar zones that are adjacent ate perfect for this bug/feature.
