I've got my Flex schedule to run at 11:45pm if needed. I figured that the system would look at the data for the weather during the day and then make it's calculation / decision when and how long to water. I thought that if I moved the start to 12:05am it wouldn't recognize the rain / weather that occurred the previous day. Is this wrong logic? Or does the system look back 24 hours before your set run time no matter what time of day it is? Or is there a set time of day that Rachio runs the calculation to run or not?
