I imagine you're right. The numbers might change by a point or 2... I mean that one letter (F) I have only 1 point in might change, but the others look pretty solid. I should probably read the ISTJ description too just to be on the safe side LOL.
Scratch that. The "F" wasn't the one I got 1 point on, it was the "S"... so taking the test again so soon seems rather fruitless, as it may be swayed by "trying" to get a certain type, rather than the honest answers I did give. I was distracted the first time by my little one coloring on my lap, but I did read each and every question.
