I'm sorry to say, but they can't. It would be one thing if, for you as an individual, the error was always consistent (e.g., "always five hours ahead"). Then at least you would be able to track trends over time. Sadly, the technology itself is not reliable in that way and should never be relied on to track trends.

Perhaps not. My subjective experience of my Withings scale is that the reported fat percentage has at least remained where I've expected given my general activity level. ie, fat percentage goes up when I'm sedentary, down when I'm active.

But it's more a curiosity than a useful metric regardless.

I strongly encourage you to disregard the bf% information that scale provides you, even if it is only a passing curiosity. It can and will taint your general understanding of the body and your relationship with fitness. I would recommend even disabling it entirely if possible, and would even recommend replacing it with a non-"smart" scale if the option is at all economical for you. I'm happy to explore the subject further and suggest alternatives if you so desire

Honestly I don't care enough. If I happen to be in the interface I'll probably turn it off, sure. It doesn't inform any decisions, I barely register that the number exists.

Excellent, I encourage you to never deviate from this path
