Went through the mood tuning files for the new update; seems like there was no change since when I first posted those numbers.
The tunings, if anyone wants to take a look, are the ones that start with Mood_ . Search for intensity_thresholds inside the file and you will find the thresholds.
Furious doesn't seem to be the name of an emotional state, but instead the name of the permanent (almost; 100K minutes) Angry buff that can only be obtained by cheating.
(If anyone wants to test it, the name of the buff is CheatingIntensityBuff_Furious, but be sure you either do it in a separate save or know how to remove it, since it is intensity 4 and should last about 70 sim days.)
Sad and Angry (and Inspired) do have more possible states, but those extra states replace the default ones and are tied to traits: Gloomy, Hot-headed, and Muser.
(Still verifying if I need to update my personal mods to the new patch, so I can't quite test anything in-game yet.)
