I tend to think this test is not so preference based, but measures trends in preferences, on a more personal basis. If you took the test carefully, I would typically try considering your result, however the concept it already has in of itself is very nice. The point along MBTI is not that you get a result and say "no, I'm not extroverted or ethical" for instance, but to realize that correlationally "I have a lot in common with this type thought process and stereotype" and that typology at this stage isn't necessarily about simple dichotomies, when there is something that tests your thought process much more analytically, it could easily be a safe bet to say you are that type, supposing that you have thought about it accurately, that type being a real personality, not just four dichotomies, but shown here: twenty or so?
The daily is sort of how you might tend to see yourself, and the tone I think is how you come across in other aspects, but might be unaware of, even if its the same type. Or in another sense, how you were brought up, and things that still might be lingering. Where as the result is supposed to be your actual type based on correlation, not necessarily how you act completely, but your mindset especially. One would expect to become more and more like this type as they develop. But as I said, taking the test carefully and thoughtfully would yield better results, if you really trust your thoughts.
Actually if you take it quickly, then sort of go back and tweak your answers a little bit to make sense, then you might get it to be more accurate. But sometimes completely retaking and overthinking yields horrible results. I guess it just depends on what kind of test taker you are. I tweaked my answers a bit via thinking deeper about myself and spent 35 minutes on it, but I still got the same result as I did when I breezed through using my instinct.
My result: INTJ (Logical, Philosophical)
Daily: INTP (Logical, Conceptual)
Tone: ISTP (Lethargical, Conceptual)
