This is a tough one, having this restriction really limits flex or our new concept of water as needed. I hope someday these somewhat pointless restrictions are a thing of the past. I think initially, your best bet after 2.5 is released, is to create a fixed schedule that runs on Tuesday/Saturdays and starts early morning hours. Based on our recommendations, you can increase/decrease watering minutes if you see fit. Our climate skip, cycle soak, and rain skip are part of the normal smart watering features that each new schedule will have on by default. These options alone will probably save you a lot of water. You can try flex, but with only two days of allowed watering, it will more than likely water on each day since it knows it can't water until quite some time. The 2.5 release is only a few days away.
Without knowing more about these areas I can't really comment. It seems like if you gardens are getting what they need for this configuration, I would stick with it
Glad to hear , and welcome to the community!
