INTJ
No Tut, you are an ISTJ, there is nothing INTJ like about your personality. You think in concrete terms even when you are trying to be abstract. In all our old conversation you screamed ISTJ at me in all your replies, the same type as my ex husband lol.

You can reduce the flaws my taking into account your percentage figures, so if you can see if you display exagerated traits or not, that way you can take more out of the results.
The key to it is understanding the data, that way you can take from it what you wish..
Or, use the cognitive functions to determine your type.
I thought I was an INFP for a few years, always got INFP in the tests, but others thought I was an ENFP so I i the cog test, an my order of functions is actually NeFi, rather than FiNe which is what it would be if I was an INFP. Still the Ne and Fi are pretty neck a neck so I am a bit of both, but definitely an xNFP.
