While the use of functions changes constantly, there are also ... centers of oscillation, states that are sort of more stable than others, and various life values, philosophies etc tend to develop around these states. So this whole thing might be possible to reverse-engineer into advanced knowledge of funtions, maybe.
I have noticed this cluster type thing you are talking about but have not been able to come up with a clear understanding of it.. lately I have been thinking it may just be some enneagram type, instinctual stacking and health level combo.. not sure though. I would like to look into it more but I wouldnt want to be the one to go weeding through all the threads of what's my type. I'll read it if you decide to do it cause I think its an intersting idea.
