The results vary so much because a fundamental tenet of Myers-Briggs is that Intro/Extroversion and all the other things they claim to measure aren't normally distributed.
It's as if you measured height and had to classify everyone into tall or short because your theory suggests that no-one is average height. Obviously most people are going to be actually hovering around the average but the minor variations in height and measurement combined with an abitrary cutoff mean that one day large chunks of people will be "tall" and the next they'll be "short" and vice versa.
And yet, based on your testing, one day you'll be telling these people they'd be ideally suited to basketball, then next suggesting they become jockeys.
