Open door, meet roundhouse kick.
The description fails to recognize the fact that the Ti/Fe valuing IxTx types do communicate emotive content with their messages. This is annoying because it seems to be a characteristic going completely under the radar with no one ever noticing it despite it is so obviously there.
There is no substance to "4D Ti" beyond singaling T and I anyway. Your version is better, though, because it is less obfuscatory.I always thought it was based on a combination of I/E and F/T.
