Doomer You have a point, however there are, again, RL examples where paperwork will lead to similar situations.
Here is one : in my country, teachers cannot give full mark to students (at national exams) without filling forms to explain why the kid deserves a perfect grade. Since it would be a bother, most opt to not do it and take out a point on some detail.
If you apply a similar logic, raising her from the lowest rank to the highest might 1) force him to do additional paperwork to explain his judgement, 2) would be way easier to oppose by opponents to the idea from the highest levels of the guild.
Beside, he has legitimate reasons to “fail” her: her physical examination is rather poor and her basic knowledge abysmally low.
