I know that intuitively you would think this change would help, but things get pretty screwy when your soil settings are off. I’d recommend trying to go back to what you truly think the soil is. If you haven’t already, use the Web Soil Survey guide. Then follow up and make sure that the rest of your settings are pretty close, especially root depth and precipitation rate. Once you have all that set look at your moisture graph again and see what it’s predicting. Tweaks are easier once all that stuff is close to reality.
As an example, here is my chart from this week, when temps were hovering around 100F. You can see that it irrigated every third day.
This coming week temps are climbing to the 111-115F range. It is predicting every other day. In some cases it will actually go for two days in a row, then take a day off.
