I found that the fat percentage was largely unhelpful.
While I doubt that the number my scale tells me is my true real body fat percentage, it is consistent and repeatable and does allow me to accurately monitor
changes and adjust my diet and exercise regimes accordingly.
Whatever my true body fat percentage is, I am satisfied with what is is now. I think at the age of 70 years I am more fit now than I have ever been. So as long as my scale confirms that my fat percentage is not changing, I'm happy.
