For the purposes of this post, assume the above are not faked (I agree with jendoly, if it is faked, wow, that's a lot of effort). It was suggested that perhaps the results were being sent out by area of study, but then there was the result of 1, and only 1 aero award. It was then suggested that perhaps only awards from certain sponsors were being sent out, though overall the number of results seemed low.
I just looked over the distribution of awards by area of study and sponsor and what occurs to me is this: though the Army, Navy and Air Force sponsor quite a few (~60 each), there is a fourth sponsor - the High Performance Computing Modernization Office. They sponsor on the order of 10 awards each year, and, despite their name, sponsor awards in a variety of fields. Perhaps they were the only office to get their list in on time? Did we ever get confirmation that a full list was received, or just a vague promise from the NDSEG that "results would be released"?
