So, most of us started with a controller with fixed days and schedules. How about we enter those (and the current season, etc.), and have the app ... or an app on the website ... translate that to a proposed Fixed or Flex schedule?
There should be some sort of explanation as to how the schedule was developed.
I suggest this because the initial Fixed schedule proposed was for my shrubs on sprinkler heads to get 59 minutes 3x per week, whereas I actually run them 6 minutes. Clearly I've done something wrong ... I hope. I might even have to watch the video.
You're probably doing this calculation already, but if we could see how the zone settings and location influence the times, it would help.
