Why is the touch so incredible inaccurate? What is the math behind this showing TWICE the actual body fat according to 4 other measures (BodPod, Dexa, Tanita, and a 7 point caliper test). All of those tests were in agreement by 2%...the Touch DOUBLES those values. If someone didn't have the resources I have to calibrate bodyfat, they would be profoundly disheartened and likely not bother exercising. I can see being up to 4% off, but not 200% off. Did you guys rush this product out before testing it?
