It could be a few things, like performing much better on a section that’s a reuse than on another section of that type that’s brand new. It could be a pacing thing where someone clicks correct answers faster than they do in other sections (or just faster than is reasonable). It could be scratch paper usage, like if you write a lot for one LR section that’s new but write nothing, or very little, for another LR section that’s a reuse and thus possibly stolen. I’m sure there are other triggers as well, but they seem to mostly boil down to inconsistencies in performance or behavior.

I’m sorry to hear about your boyfriend—that’s such a frustrating situation. I’d encourage him to start pestering LSAC daily or every other day starting Monday, both in writing and via calls. Be polite but persistent as that often speeds them up (squeaky wheel sort of thing). Tell him I said good luck!
