Well I tried that other site and it had me at 22% fat, when the linear-software one had me at 23.5% - but the other site doesn't take account of height, which can't be right.

Now I've got a problem with the linear-software site, which I always thought was about right.
My neck measurements have gone down, cos I've lost fat from there too. I've just altered this dimension and this has put my body fat UP!!!
So now it reckons I'm 24.7% fat. Yet I look quite a lot thinner (have less fat on me), than someone whose bodyfat is 22.5% as far as you can judge by photos. Hmmmm.

So now I don't know what to think. I want to measure body fat, cos when (if ever ) I finally get back to the gym, the extra muscle will make me heavier, but I should be losing fat still, so weight on its own won't work.
Help!!
