harmi, harmi, harmi: You are still obsessing over LOA. Think of it this way: If USNA perceives they need a quarterback, Greek speaking female who can lift 500 pounds, more kids from somewhere, some state, etc........these folks may get LOA's. There is no formula. No way anyone outside of Admissions can predict the chances of their kid or anybody's kid getting LOA.
Not to rain on your parade, but academics are just one of many facets. That Whole Candidate Score takes into account interview with BGO, extra curriculars, sports, recommendations from English and Math teachers as well as a rating of just how tough your high school is.
Rest assured, Admissions is full to the gills with valedictorians with eye popping SAT's, many extra curriculars, pt studs, etc. who can gain admission to any college or university in the land. One of my clients had a son applying at the same time as my son. His did not get offered an appt to USNA. Mine did. His kid's ACT was two points higher. Can't tell you anything about the rest of the boys statistics. But client just tells people, "My boy's SAT was XX and he did not get offered an appintment to USNA. What more could they want?" The short answer is "a lot!"
So, add this information to the fact that your child will likely compete on a slate of ten nominees from his/her congressional district/state. What if there's one on that slate who matches stats one by one with your child, yet has a few more pullups. Or the math teacher was more enthusiastic in their assessment.
In short, there are a myriad of factors you cannot control. You can control one thing: your application package. Make it as strong as possible. In every way. Take and retake the standardized tests. Re-do the CFA.
Now, repeat after me: "We do not expect to know anything until mid March."
