What happens when an APFT run route is found to be too long after the fact?

We're having this conversation at my current duty station, not for a past APFT, but for one planned for Thursday. Its surprising to see 19 responses to your question but not a single doctrinal reference or reference to regulations.
AR 350-1, Paragraph G-9 m(2): A minimum of 4 months will separate record tests.
So you can't take another record APFT for four months, per the regulation.
FM 7-22, Appendix A, Paragraph A-17: There is no requirement to survey 2-mile run courses; however, selected test sites should be free of significant hazards such as traffic, slippery road surfaces, and areas where heavy pollution is present.
So the Army is ok with your unit using a track that ends up being 2.05 miles. Close enough is close enough, according to the Army.

I would go on a long tirade about how nothing is perfect in life, pushing yourself...um, working out, and blah blah blah. Fair is fair, just remeasure it and hope they pass it next time. Why even bother thinking about motivating them to try harder when we can all be winners? They are obviously more concerned with the length of the track than the fact they would have barely passed that shit anyway, lol.

My old unit had a similar problem, except it was eighty meters too short. I was HHC Brigade, so Brigade Commander rejected the outcome and had the whole unit retest two months from then as they made an accurate new route. Those soldiers who were looked at an individual basis and were given an option to make an appointment within two weeks to retest on the new route. I'm with SGT Welsh, and those who failed be given a re do and anyone who wants to retake it for school or promotion, should be allowed to take it again.
