It will definitely require more observations of subtypes like SEI-Fe to see what behaviours stay the same in case of strengthened extroversion.
Therefore concluding if person is introverted or extroverted based on his behaviour doesn't tell about his type or base function but about strength of extroverted function. At least by measuring by current definitions and tests. And that's the reason why these tests are so non-reliable.
