I've not seen this mentioned by anyone else and am wondering about the accuracy of these measurements.

From my understanding there is no exact way to measure BF% except with sophisticated equipment in a lab setting. With that said, there are a few ways to estimate BF. I'd say the best would be Hydrostatic Weighing (+/-1.5% accuracy). You are submerged in water to get a reading. You probably have something like this at a university near you. Skin fold calipers are okay, but the measurements have to be done by a trained individual that knows exactly what they are doing.
My personal observation of the technique you are describing will give you a good reading within 5-10% of the true reading. But with me, when I hold the monitor to get a reading it is always lower than if I use a scale that you stand on that measures body fat. Those are always higher for me. My theory is that I carry more fat in my lower body than my upper body and the way they work is by sending an electronic current through your body and measuring the return rate. So through one arm and down the other. Or up one leg and down the other. I'm 26% BF on the monitor you hold and 32% BF on the one you stand on. So I just average it and go from there.
I think the most important take away is that if you are looking for a REAL number, go check out the hydrostatic weighing method. If you want a general number to start with to measure your progress, use the number they give you realizing that its not exact. Especially if you hold your weight either in your upper body or lower body.
Just my thoughts. Hope that helps.
