Sorry for the late reply. I intended to reply here last night but i conked out, and just came back from work.
Anyway, at this point, i'm pretty confident about the 9 wing on the 1. It's quite clear in the Rebel Wisdom video and maybe even more in the triggernometry one.
She is indeed, as Roshan pointed out, a lot less reactive and attached when she is not with Ben. It seems pretty clear in her interactions with her business partner and with the two alpha introverts that her head fix is 5w6(6w7).
And then her heart has to be 2w1 rather than 3w4 because she really has to have more than a subwing in the 1/2 "cutting edge" space. Part of the reason i initially leaned toward 3 for her heart was the very pragmatic and almost "business oriented" way she was talking about relationships,
here for example. But I do agree with Sarah about the forcefulness behind her composure. She is also very clear that she is doing what she does not only
as a mother, but basically
for her daughter, her "skin in the game", which also seems 2(w1) >>> 3(w4). Also triple mastery and "Mission Control" doesn't seem quite right to me. Pandora's Toolbox makes more sense imo.
Stacking-wise It seems quite clear that she won't let her So interferes
Vincent too much with her sp. From the article i linked above : "Mary Harrington is a mother, political blogger and Eastern Region Secretary for the Social Democratic Party.". In that order. Mid-range stacking definitely seems right to me. So i do agree with the proposed sp/so 1w9(2w1) 5w6(6w7) 2w1(3w2) typing.
