I've been also working out at the gym a lot for my upper body so I am fairly muscular (as much as you could expect for weighing so little!). I know that I don't always drink as much water as I should and that definately affects the results.

For my wife the reading is way higher than it could possibly be. But she also drinks TONS of water (actually I wish it was water, but she guzzles Perrier ). We both plan on getting a hydrostatic test done so that we have a better frame of reference.

edit: a little while ago after I hadn't been at the gym for a few months I had the caliper test done and came in at I think 15%. Since then I've lost about 8 pounds and build back up my upper body, so less weight and more muscle, 5% could be just about right. I haven't had the test redone.
