I'm not a PT god, I despise running in my advanced years, so I don't. But the navy can go piss up a hawser as far as their test. If someone fails by 1 second on the run it can wreck their career for years, same as 1% over on body fat. Yet we will use the most inaccurate measurements possible for those items. I have run the 1.5 mile run on 1.25 mile and 1.8 mile courses. I failed PT twice back in 01-02, once on my own damn fault, the second after 6 months of working hard, but it was mid-April on the aforementioned 1.8 mile course, 2 pm and 93 degrees, I wasn't sweating, just turning red and there was no doc. Regulations for that heat( 1 degree shy of black flag) are PT for those acclimated 12 weeks prior. 12 weeks prior I was working on a helo head in sleet and rain. So basically every burden of regulation lands on the member, how we run the program? Who knows.
LOL for a selection board, I had an eval first line that was verbatim "Would be ranked much higher if not a two time PFA failure." LOL. Basically in 2001 I was on track to be the 8 year chief. I at that eval until at least 2007, got out in 2008 when I probably had a good shot. Don't mind, it was my doing.
The BMI part eats me. When I failed that first PT I was 230-ish with no muscle tone, I lived on restaurant food, did no exercise and ate constantly. But hey, I had a 19" neck! 18% BF. Nowadays I am 225, a lot more upper body due to my job, not fat in the midsection and eat a lot more sparingly. But my neck is no longer fat and measures 1-3" less depending on who is taping. Fattest part of my gut tapes 38-40. I wear 38 pants because no one makes 37s anymore. They fall off. But since I don't inflate my neck or suck in my gut I tape out to max acceptable BF of 22% Yeah, no. Chest is 50", waist 38" thinking that if I am 22 what is the guy with his gut hanging out of his t-shirt? Oh wait, 20" neck, you're good fatboy.
