Seems to me based on the service assessment that there may be a push to make "tornado emergency" a separate warning per recommendation 2.
They clearly state they want to maintain the existing POD but want to "provide a non-routine warning mechanism that prompts people to take immediate life saving action in extreme events like strong to violent tornadoes"
Also to modify the warning structure to be more impact based than phenomenon based.
All of the above would be great I think.
