I have forwarded your request to our R&D. Actually Netro algorithm has taken the high temperature into consideration and improved the watering time. We will discuss about it as some users report that there is too much water.
A simple mix of being able to adjust the automatic timings would be so helpful in fine tuning the watering needs when you have overlapping zones, etc.
Thanks and our R&D are working on it.
We will support this feature next month in the next release.
