I don't have any of the stats but keep in mind, based on some post-board comments from past board members and AFRS, that there are at least 15 scored sub-categories, bunched fairly equally into 3 major categories (Education/Aptitude, Experience, and Potential/Adaptability), that are part of the board scoring process. Of those 15 or so, only a couple involve actual hard numbers (GPA, AFOQT, PCSM) while the rest are somewhat subjective evaluation of things like experience, education type/class content, LOR comments, previous job experience, interviewer comments, communication skills, etc.). Drawing conclusions based simply on numbers may reveal information about only 15-20% or so of the boards scoring (if there are roughly 15 sub-categories, then each would only be about 7% of the total, although on any given board the actual weight may shift slightly based on needs). I've seen applicants with very high AFOQT and PCSM scores be non-selects, and others with scores below 20 get selected. Don't get fixated on the numbers.
