Evolution of the Candidate Multiple
The various preditors and weights contributing to the Candidate Multiple are available on-line with a little digging. Here are four (4) sources -- all graduate Thesis from the Naval Postgraduate School:
1) "The Performance of Preparatory School Candidates at the United States Naval Academy" by Brian S. FitzPatrick dated September 2001.
2) "The Utility of Personality Measures in the Admissions Process at the United States Naval Academy" by Foster & Pashneh-Tala dated June 2002.
3) "The Impact of the Summer Seminar Program on Midshipman Performance: Does Summer Seminar Participation Influence Success at the Naval Academy?" by Michael A. Norton dated June 2004.
4) "The Retention of Female Unrestricted Line Officers" by Elena G. Pecenco dated March 2005.
In all four (4) papers, the authors share the Candidate Multiple predictor weighting that was in effect at the time of publication.

Haven't found anything more recent than 2005, but it's pretty clear your SAT/ACT Math score is at least twice as important as your SAT/ACT Verbal Score.
Your class rank is considered a better measure of your academic performance than your GPA.
