Here’s another perspective. Leave the stats out of it for a moment.
To be in play for an offer of appointment, the applicant must be medically (DODMERB qualified or DQ waivered), physically (acceptable score on CFA), scholastically (test scores, GPA, classes taken, all the other stuff in leadership, participation in various things) + at least one nomination. (Note: USCGA is not required to participate in nom system.
The real selection pool, then, is that group who is fully qualified with a nom.
The elected officials have no role in evaluating the other qualifications. That is the responsibility of the SA. The elected officials use any method they wish to evaluate, and choose how they want to submit their slate.
The nom process is a parallel activity to all the other application and evaluation activity going on. The nom process is a straightforward linear set of steps. All the other stuff done by the SA is going on in multiple parallel and sequential processes. Med waivers can still be hanging into April.
There are also several different nom sources. The service-related ones are a simple matter of eligibility. Some eligible for a Presidential can get their application rolling early, see the Presidential nom pop up in their portal, while still working their way through DODMERB, CFA, test score submission, etc.
If you haven’t yet read the Stickies at the very top of the Nominations and DODMERB forums, I recommend it.
