Like seriously, what is one gonna do when someone isn't a stereotype of both their Socio and Psychosophy types? Make another system to explain the variables of a combined Socionics and Psychosophy type? Well, they actually kinda do that. If you are not Willful enough for a 2W yet somehow fit into the already buttery structure of a 2W type, you become 2W with a 4W subtype...
Like... what? At least Gurdjieff's centers had the excuse of lacking a formal structure, it can get away with vagueness (funny enough, PY is really just a rip off of his 4 centers). But if vagueness is useful, then just use it as
Tarot cards for creativity, not an actual subtyping to make meaningful predictions
