I just took the humanmetrics Jung test at http://www.humanmetrics.com/cgi-win/JTypes1.htm. My results are:

Your Type is
ENTJ
Strength of the preferences %
Extroverted 1
Intuitive 44
Thinking 33
Judging 1

This one was only 72 questions, so I also leave plenty of room for error, but it uses classic yes or no answers, rather than a scale of 1-5, which may seem less accurate, but it isn't confused by error caused by calculating the difference between lots of "4" answers and lots of "5" answers. I mean, if you rarely use 5, but use 1-4 commonly, it will tend to rate you further toward the negative side of things, simply because you don't use the strong affirmitive enough. Yes/No gets rid of this confusion. I suppose I may have slipped into E and J, but I know myself well enough to know that INTP characterizes me more than ENTJ. The 16 types don't take into account borderline cases, but there isn't much they can do. It would have to write a 3x3x3x3 chart, rather than a 2x2x2x2 chart to take into account borderline cases, and 81 different personality types is just incredibly unhelpful to create.
