Just was looking at my zones in the web app this morning, and I noticed that the root depth for all of my grass zones were showing as 9 inches. I thought that the default setting for Bermuda was 6 inches, and I don't remember going through and changing any of these.
I don't know if you have access to historical setting data, but if the settings changed due to some server error during the 'do we flex/do we not flex' stuff then people need to know so they can double check their settings.
I won't make any changes until I hear back. Don't want to destroy forensic data.
