Bodyfat results can vary no matter what the method. Two different people could measure you on the same day using the same method and probably come up with different bf%. And when you compare one method of measurement to another, the results vary widely. Don't get too caught up in that % number. Just use it to judge an overall trend of whether it's rising or falling.
I've had the same person measure me for the past 3 years and I've kept all the caliper measurements for the different sites. I look at these more than the final %, but they can be iffy because a millimeter is so small, and whether you're measured in the same spot the same way, etc. Lots of variables even when using the same person and the same method. It's fun to get a number, but I think progress pictures are the most telling.
Remember that muscle is denser than fat, so a pound of muscle takes up less space than a pound of fat. Say you replace 5 pounds of fat with 5 pounds of muscle. The scale would stay the same, but your measurements like Arm - ??" would be getting smaller.
