The big problem with these results (and god knows I've analysed enough of them) is that the extent that they map to other characteristics measured without surveys is pretty much unknown.
If you want to create a new measure of extraversion, then you use the older methods (i.e. other surveys), and this only really tells you that the new measure correlates with the old.
I vaguely recall Eysenck doing physiological tests for extraversion/introversion which would avoid this problem, but I'm not aware of any more recent research in this area (mind you, I've been out of the field for a decade now).
