No. You're still thinking in terms of non-flex schedules.
I don't tell my flex schedule which zones to run, nor do I tell each zone how many minutes. The Iro figures it out automatically. Which days watering is done, which zones are included, how many cycles are needed, how many minutes per cycle, and how many soak periods are all managed by the flex schedule. All I do is tell it what kind of soil, what kind of plants, what's the slope, how much sunshine, etc.
The hard thing to get used to is to then let it run on auto. What will happen is flex schedule will carefully use weather data to custom 'season adjust' every day's watering details - which zones, # of cycles, minutes, soak periods, etc.
The harder thing to do is then make incremental adjustments. You'll find some zones aren't getting enough water, other's too much. Now you've got to figure out what to adjust. The interface for doing this isn't easy to understand (% depletion, % efficiency, % overall adjustment, changing plant material, changing soil, etc.
The hardest thing is to work around still some bugs. For example you're going to get confused when the forecast calls for rain, it doesn't rain, and it takes 3 days for the Iro to recover, assuming you can hold yourself back from diving right in to make manual adjustments.
I start watering at 12:15 AM, every day, and 'let 'er rip.' Some day I hope for an already requested 'don't water when the sun's out' enhancement so that if watering is continuing at 7 AM, flex schedule momentarily pauses until 7 PM, then resumes. Right now flex schedule just keeps on rotating around, unwilling to pause for anything.
Give me another 12 months, and I'll have all 13 months of this chart filled out, to show exactly how flex scheduling works: http://www.welserver.com/perl/plot/WEL0343/Sprinkler1.png . Here you can see that for the last month and a half I've been flex scheduling, the amount of watering varies significantly by day, as weather patterns change, different plants/trees/grass/flowers need water at different times, etc.
