It doesn't work like that?
Actually, now that I think about it is more like a ying/yang ... if you go left for extroversion then the you have [major space]/[minor quantity] and if you go lft then you have [major quantity]/[minor space]. For introversion it would be [major time]/[minor quality] and [major quality]/[minor time].

So, my answer is that both are used for each category, but I think you were on the right track when you thought what you did.
