Why would they want to do that? If what you are saying is true they will be forcing themselves to select less qualified candidates to meet the numbers. The high guys with better packages will be waiting in line behind people with crappy ones who happened to apply sooner.
You are not making any sense. They look at the whole package, there are people who get selected with lower gpa's and lower ASTB scores than you and vice versa. Always have and always will, but it does not mean the people selected are more qualified or less qualified.
There are people with 3.8 GPA's and 9/9/9 ASTB's that will get non-selects. There is no way to game the system...just apply as often as you can and see how it plays out.
