I want to say that I've scored as a 2, a 6, and maybe a 9, but I've also consistently scored high on 4 and 5. Bear in mind these are all on free online tests.
If I ignore test results and just go by description, I would guess that I'm a 4w5. The 4 definitely makes the most sense in terms of integration and stress (1 and 2, respectively).
The one thing that I am absolutely certain of is that I'm not an 8.
