Most of the attempts at artificially establishing the latter were either theoretical (like "gut triad types must be Sensing" - ridiculous, if only considering the amount of xII 9s), or based on exclusion (like "ESEs can't be 6s" - except they can.. though some combinations seem improbable). They fail.
Also, I think most Enneagram descriptions are detached from the basics of the system, or focusing too much on mental processes rather than motivations, bringing it closer to typologies based on Jung's theories at the cost of losing its original meaning (and usefulness).
