So, generally, if a scale says around 13-14% it's actually like 9-10%? I got it done at a Jenny Craig on one of their wave-emitted scales.
Why was I at Jenny Craig, you ask? It's right next door to GNC, and I asked the GNC guy if they had bf% scales or calipers, and he told me to try next door, at the Jenny Craig.
It did come up as like 13.8%, but that was back like 4 months ago, and when I had since used calipers I showed about 10% bf. I doubt I have the resources to do the tank method, but I don't need it THAT accurate.
