One more question about using different State settings. Could you share some real life examples when to use:

Learn Only - my understanding is that it's useful when DDoS is first enabled and when Full Automatic/Auto Detection mode is planned to be used in the future. Does it make any sense if Full Manual will be used?
Detect Only - seems to be more useful as it creates Alerts (in opposite to Learn Only) so it allows for better understanding if there are attacks or what could be false positive

You never mentioned Manual Detection/Auto Mitigation - is that because this mode is not really useful?
