To add to this, the parent can also be a participating reservists with a point summary totaling at least 8 years of service or a retired reservist eligible for retired pay but not drawing yet because they haven't reached age 60 (the year they can draw reserve retirement pay)
One note about the reservists, the form that is available from the Academies lays out the requirements. You must have at least 2880 points. You basically get one point a day for each day of training, orders, or active duty time. A typical reservists gets about 75 points per year so in order to get to 2880 you have to have active duty time or lots of deployments. I have 23 years, 7 of it active and have about 3500 points.
With regards to the question about "stats" thanks for all the input. The only question I didn't see answered was "When did they complete their application?" I am guessing most if not all are done no later than early September. And lots of smoke, mirrors, praying, and magic.
