Target Rollover Methodology

Inputs and outputs

Formula

if rollover disabled: no adjustment
if no logged meals yesterday: no adjustment
calorie overage adjustment = -min(actual - target, cap, target - 1200)
calorie cap = min(300, max(150, base_calories * 0.15))
protein deficit adjustment = min(target - actual, min(35, max(5, target * 0.25)))
fiber deficit adjustment = min(target - actual, min(12, max(3, target * 0.30)))
sugar overage adjustment = -min(actual - target, target - 10, min(10, max(3, target * 0.25)))
saturated fat overage adjustment = -min(actual - target, target - 5, min(6, max(2, target * 0.30)))
extracted omega-6 oil overage adjustment = -min(actual - target, target - 3, min(5, max(1, target * 0.30)))

Calculation steps

1. Read yesterday logged meals only.
2. Compare yesterday totals against persistent base targets.
3. Apply capped corrections for one day.
4. Never read today adjusted targets as the next base. This keeps rollover stateless and prevents repeated carry-forward.

Guardrails

• Rollover only runs when the user enables it.
• It does not punish missing data; no logged meals means no rollover.
• Calories are never rolled below the 1200 kcal floor.
