My error levels are values in avarage for time of 4 hour / 1 day / 3 day in percentage (0.01=1%, 0.5=50%, 0.99=99%).
That means if you have 0.5/0.3/0.1, your error level is rising!
If you have 0.1/0.3/0.2, your error level is okay.
Above 0.55 you should engage and optimize your website.
Same is for anomaly status, but that is not an error level. If your anomaly status is rising, it could be an error or you just changed some important things on your website. You should restart the AI training if you have changed a lot in the user experience of your website.
