Yes, 9 would be my core. I think I'm 952, so that plays too I guess.
I rarely relate to people, tho some only make "???" appear in my head, like you. I guess "relate" isn't truly what I meant, sorry about that. Confusion is what I should have said, like looking at a missing piece and trying to make sense of it. That's pretty much what a blind spot is, lol.
