Should there be exceptions to policy allowed for not meeting height/weight requirements outlined in AR600-9 (Army Body Composition Program)?

If the Army is not going to change the way it measures body fat (even though studies have shown that it can vary by as much as 15%, plus or minus*), then should there be exceptions to the policy? First of all, it is perplexing to me that Company Commanders are trusted to conduct investigations into allegations of sexual assault as well as act as the judge and jury, but the exception to policy authority concerning body composition is the DCS, G-1**. Here's an idea, if the Soldier can pass the APFT, then he or she is exempt from meeting height/weight requirements. If that is not tough enough, then how about if the Soldier scores above a 225 on the APFT then he/she is exempt from meeting height/weight requirements? Another idea would be that if a Soldier does not meet the body fat standards, then he or she can schedule an appointment with a certified dietician that uses a more accurate method to measure body fat, i.e. the caliper or hydrostatic body fat testing, and if they pass using those methods, then the Company Commander can grant the exception to policy, not the DCS, G-1. Your thoughts?
