Will Rachio reduce watering TIME according to weather?

Our city is on water restriction so we can only water two days a week. So, iet’s say we get 1/4" of rain the day before we are allowed to water. Would Rachio water water the same amount as if we had no rain? Then let’s say that the day prior to our 2nd day of allowed watering we get another 1/4". Let’s say the temp never gets under 95 for the entire week. Would Rachio still water the full amount or just skip watering altogether? How would Rachio react to those conditions? Maybe I don’t understand your technology, but it seems to me that either Rachio would skip both waterings and we would only get a total of 1/2", which is way short of what would be needed. Or, it would water the same amount as if there had been no rain, which would waste water. Am I correct? I’ve had my Skydrop for 2 years and it has consistently reduced my water bill while still keeping my grass lush and green. I just don’t see how Rachio will reduce my water bill, which is my goal.
