It is hard to stratify where the UPT grads stack up against their class mates and to claim they are middle of their class. First off you had lots of T-38 guys going into the platform and so typically they would be top-third to top-half of their T-6 class by default. However from the T-1 T-44 classes the guys that seem to be getting RPAs are the bottom of the barrel unless someone in the middle or bottom third "volunteers"(i.e. are the only person(s) to not put them as the last two choices on their dream sheet.) Also, among those it seems to be the trend that the guys who "volunteer" seem to do things like put Creech 8 out of 22 and Cannon like 16 out of 22.
The BIGGEST problem I see moving forward though is having two different career fields doing the exact same job. With the only way to minimize that being to make it so the only rated pilots in the RPA community are the ones who volunteer for it. That way they have no reason to gripe about the differences, because they volunteered to be in that situation.
