First off as a parent of a USNA Mid, the AFA is not very different when it comes to the AFA.
SAs are all the same highest WCS on a slate wins.
All SA's want the well rounded candidate.
do other SA parents have sons and daughter serving at more than one academies?
That made me chuckle.
There are parents on here who served in one branch an their child is now attempting to enter another branch.
Our very good friend is an AFA grad, his son is a mid at USNA, in bagpipe and drums, they fly out for every home game that fits in their schedule(Dad is a United pilot), but yet he tells his DS constantly, at least the AFA doesn't wear skirts! Now if you or I slammed the USNA he would ream us, but that's just how it works.
There are family members that serve in other branches, and just like siblings they love to egg each other on. I know at least 3 posters here who have children in different branches or 1 is at an SA and the other ROTC.
In the end there is a common bond of serving the nation and nobody cares if you are in the AF, Navy, Army, Marines or CG. It is all about the fact that you are willing to defend this country,
BTW you are a head of the game compared to any other sophomore because you understand how the WCS works. You understand that the rigor of her curriculum matters, and that she can't just be the 4.0 gpa student without ECS. Or that her CFA is going to count.
Your experience as a parent who lived it with your other child will be able to guide her.
I do not know if your DS went through SLS, but I would advise you to have her apply for that next yr.
