Like many others have said here, it really does appear as though this new system is going to be a step backwards. That, or there doesn't seem to be enough clarity about how the new system will work.
I've been a happy user of the Flex schedule for the past 9 months. It has worked beautifully, automatically skipping and adjusting durations based on my current weather conditions, all while abiding by my city's restrictions to only water on certain days.
Like I've done before, what I want to do is tell you what I have in each zone (grass, soil, nozzles, etc.) and which days of the week I'm allowed to water, and then leave it to your computer algorithms to decide how long to water and when, based on my current, actual weather conditions (not necessarily the 30-year average). Is this going to be possible with the new system? If not, can you please explain how a user like me is actually benefitting from the new system?
