To add mystery to the madness, I believe there is a distinct difference between our "typological preferential" use of the functions and our "skill level" of the functions. I believe our skill level is measured by the Cognitive Processes test, our "type preference" is imperfectly measured by MBTI tests and the like. I'd expect to see one's skill level in a particular function high if it's their dominant or auxiliary though. But life experience may have us gain skill in other functions moreso.
Then again I'm one of those crazies who believes deep down that everyone has a "root" type, it just might not be evident to them, especially later on when they've become a more complex person.
