Good validity at the population level doesn't mean it'll be perfect for you, and inaccurate results for you don't mean that it's not valid overall. Tl dr the Navy formula is actually pretty good at the population level, but it, like all means of estimating body fat percentage, can have pretty large errors at the individual level. However, average errors can be misleading – even with the low average error of DEXA, individual errors can sometimes be 7-8%+ (and obviously individual errors can be even larger for less accurate means of estimating). Just going from memory, average error is something like 5-6% for 2-point bioelectrical impedance, 3-4% for 4-point bioelectrical impedance, callipers, and Navy formula, and 2ish% for DEXA, underwater weighing, and bod pod. The US Navy formula is better than 2-point bioelectrical impedance, similar to 4-point bioelectrical impedance and comparable to callipers (which is respectable for how simple it is), but it's not as good as underwater weighing, bod pod, or DEXA. The Army Body Fat Calculator uses the following formula to estimate body fat percentage: Body Fat Percentage 86.010 x log10(waist - neck) - 70.
