Vaticstatic, what kind of caliper are you using? If you check out my thread “Discipline Help,” you will see me going through these issues. I have a 60 dollar handheld one that seems useless (numbers are hardly changing when I know I’ve lost a good bit of fat). I also have a Fattrack caliper, and I am trying my best to be as accurate as possible with it. For example, if it says “measure halfway between x and y,” I use a tape measure to find the halfway spot. Then, it says put your fingers three inches apart to pinch, so I measure the three inches as well. I’m trying to be as accurate as possible.
TT’s solution is the best, if you can find someone that you trust, somebody that’s been doing it repetitively, that’s the way to go. But if you can’t, or at least you can’t yet, you can strive to be as accurate as possible on your own.
