1. It's a decent estimate. But it's not 100% accurate. If you want an accurate measurement, you'd need to see a doctor or a nutritionist.
2. I don't think it is 100% but it isn't that bad. If you want something more accurate ask a doctor or physician.
3. not very, it works by sending a current up one leg, across your hips, and down the other, so your upper body isn't even included the amount of water you have in your system can also affect the results....
4. One of the things I was once told by a fitness expert is that it doesn't really matter what type of body fat measurement test you use. They all have variability. BUT if you use the same test, in the same way, given by the same person, etc., whatever percent body fat loss (or gain) you experience is going to be pretty accurate, regardless of whether the baseline was 100% accurate to begin with. And after all, it's the changes that matter, not where you started out.
