200.4 lbs - 15.6% BF??

A week or so ago I took a body fat reading and got around 15.6%, which I figured was an anomaly (maybe hydration levels or moisture on my feet, etc).  So today I took another one and got 15.6%. Not sure what to make if that.  I am noticeably leaner and at 200 lbs, it would only take losing 2 or 3 lbs of fat to take me from 17/18% that I had been consistently measuring at down to this new number.  

I've been hitting the diet and lifting pretty hard, so I want to believe that % is accurate, but I'm not sure.  Time will tell I guess (if % keeps lowering and if I can see it in the mirror)
