I really think there's zero question there are different emphases/presentations of the enneagram types. Aka how you map the overall structure to reality and justify that mapping differs depending on what you want to say about reality.

And yes I've "resolved" the inconsistencies typical to my TIM,but I also get the sense my version makes high level statements rather than capturing the empirical nuances of people, which often fit into a messier system, if it can even be called a system.

You have the choice of creating categories because hey, it works intuitively and so forth, vs having a truly perfect structural reason for placing a category in a given place.
