Body fat calculation question

[rapidride3]

I had my body fat tested a while back,, it came to 15.2% my lean body mass was 170.0 lbs. if i take 170.0x.152= 25.84 lbs of fat. however 170+25.84 equals only 195.84lbs. I know for a fact i was weighing 200lbs at the time of the impedance test. What happened to the extra 4 lbs i was weighing???

Experimental error. Bodyfat testing at best is problematic. There really is only one truly reliable method: render the body. Sadly, this kills the client.
