The problem with this is that very few are going to be able to tell you what you want to know. There are too many factors, too many people going different directions and it is easy to lose touch with everyone.
My API class lost 2, Primary dropped another 2, and Advanced dropped 1. Again though those are different groups of people throughout different pipelines. In API you will have NFOs and Air Force people with you, most of whom go to other bases for training so most of the time we never hear back on how they did.
