I have no magic wand answer for you, understanding the waiting is tough.
A max of 100 Presidential appointments, no matter how many hundreds of applicants are eligible and go on to become 3Q, may be offered.
There were likely a handful of "no-brainers" with only a Pres nom who were offered appointments back in the fall.
Have you counted the number of Pres noms noted in the 2021 class appointment thread? That might give a rough estimate of Pres noms that might still be in play. Of course, that's where posters believe their nom came from, and that thread represents a small number of a typical 1100-1200 class.
If you aren't offered an appointment based on the Pres nom, you will still hang out on the NWL. USNA can continue to fill out the class from the pool, charging the appointments to a special category.
So, all that - there may be waves and wavelets or a steady stream that dies to a trickle, but no way of knowing how the Pres noms are coming out.
Tend your Plans B-D, keep an eye on your current responsibilities, have some fun while still at the top of your school heap, rack up good kid points with family. A good military skill is learning to compartmentalize things you cannot control, and being present in the here and now.
