Yes, I had this issue for my garden a couple of summers ago. As you know, with the Gen2 software there was a limitation of once-per-day watering. @franz, is it fair to say that the current Flex Daily algorithms are still limited to 1X per day? In my case, my vegetable garden was drying out such that it was always sitting at MAD.
There are other interesting parts to the Dante’s Garden discussion, but this was the result of adding a supplemental fixed schedule at the time.
Ultimately I went to a fixed-only schedule for future garden seasons. Supplementing in the afternoon with a manual watering worked when my Flex Daily would have otherwise ‘bottomed out’ (>115F temps w/loam soil). However, when Flex Daily on it’s own was was deemed to be sufficient by the algorithms the supplemental watering would throw things off. The fixed supplemental watering would fill up or even saturate the zone, and Flex Daily wouldn’t run the next morning.
In your case @Miles267 I would either leave your Bermuda as-is with only the Flex Daily schedule, or adjust your zone settings. I have Bermuda as do most here in Arizona, and we don’t need to water it more than once a day even with temps that get as high as 122F. For that matter even at 110F it often skips a day or two if you make sure it establishes deep roots, which are deeper for Bermuda than most realize. I have mine set to 9", although it has been established for some time and I’m sure our soil types differ. If you’d like you can share your settings and we can compare.
