Your measurements. Honest numbers.
Body fat, daily calories, protein, heart-rate zones — worked out from your own measurements and shown as a range, because no formula is exact.
One number is a decision someone made for you.
Pick a different formula and the answer moves by several points. A range shows that uncertainty instead of hiding it behind a confident-looking decimal — so you read the trend over weeks, not a false precision.
