I think what people sometimes forget is that our brains and our bone marrow is almost entirely fat and makes up around 5-6% of our body, but this again is just a bit the problem some will be able to do measurements that are closer to a DEXA and some will have one that's further away. It's a good tool for measuring change in bf% but yeah depending where and how often people pinch you'll have variance and almost always it'll get undercounted because you can't pinch brain matter or marrow.
