I was only quoting the report, which has those same lines for Steadfast MCs. But for my own two stories with Steadfast-Stop MCs, I can tell you those lines are super accurate. One has an excess of Uncontrolled (drive to be free) getting her into trouble, the other an excess of Control (focus*) getting him into trouble.
* BIG ASIDE THAT SHOULD PROBABLY BE A BLOG POST: it took me 150K words of my first draft before I fully understood his MC Problem of Control. I saw him as this lovelorn guy who always gets these big crushes on girls, totally smitten before he's even said hello. In the story, he's pining after the IC, and his friends are like, "here we go again" but he's like "no, this is different". It all fit Mind/Subconscious/Hope perfectly, but for Control I was taking it as "his friends keep trying to control his love life, but he wants to do it his way" which worked, but I felt like there was something deeper I was missing. As a Steadfast Mind character I felt I should also be able to express his drive without referring to what others want, but I came up empty.
Then, just a week ago, I was playing a scene in my head and the MC's friend Eric says, "Dude, we're surrounded by hot chicks, perfect targets for you, but you don't see them. You're like a laser-guided missile aimed only at Becca." Suddenly it clicked: laser-guided missile = excess of focus = Control. The MC is totally focused on one girl and nothing else.
How the hell did I not see that before? But I'm glad I found it so organically.
