@i_like_planes - the math is fuzzy. Don't get too wrapped up in it and focus on the things you control. I have seen multiple years of 5 students from the same high school go USAFA. If the math was as rigid as you initially thought - how would that work? They all have the same Congressman and 2 Senators.
Behind the scenes, USAFA can actually assign a nomination to another member of Congress. It sounds weird, and again do not focus on the small picture here. You need a nomination and that is your ticket into the next round. When it comes down to offering you an appointment, they may survey the landscape and see that Wyoming did not have enough qualified applicants this year so they assign your nomination to one seat that was originally planned for Wyoming. Did you know there are some congressional districts opposed to Service Academies and literally NEVER appoint any constituents? It happens.... and those seats to to other parts of the country.
