Hi! I. have a Gen 2. I have set up a flex monthly schedule for a few of my zones that are defined exactly the same way with rotor heads, warm season grass, etc and all other defaults. When Rachio calculate my zone run times, each is different for some reason and I’m wondering why. One of the zones is 19 minutes, one is 7 minutes, and one is 9 minutes. I haven’t done any of the advanced stuff as far as slope or measuring my zones. Any. thoughts?
