Thanks for this. The crop coefficient is at the default for each. In searching on that term, I found this Rachio page, which seems to answer my question.
What is interesting is that it appears that you can reduce the amount of time of the watering, while leaving the frequency the same; or by using the crop coefficient you can decrease (or increase) the watering frequency, but leave the time the same. I’m going to have to think about what would be best to adjust.
