Every logged week from Devin Fitness.xlsx — weight, calories & steps, plus an estimated body fat for each week. Most recent on top. The BF column is a model, not a measurement: it anchors on the Aug 3 2026 read at 150 lb (12%, range 10.5–14) and works backward, splitting each week's change into fat and lean with a ratio that gets less favourable as you get leaner. Shift the anchor and every row shifts with it.
