Complete sensitivity-range disclosure

The free range responds to the answers; statistical coverage is not yet claimed

The application first calculates a point value E. It then retests selected high-impact answers one at a time at their nearest documented response categories. Unknown health measurements are tested against documented plausible alternatives. Calculation numbers do not affect the result.

Retestsdᵢ = recalculated value − E
Allowancea = 2.5 modelled years
Marginsm = √(a² + Σ factor movement²)
Boundscurrent age ≤ L ≤ E ≤ U ≤ 110
Known responses Nearest categories are retested The largest movement in each direction is retained per factor.
Unknown measurements Documented alternatives are retested Unknown inputs can widen the displayed range.
What this band does not mean

The 2.5-year allowance and response perturbations have not yet been calibrated against independent longitudinal outcomes. The range therefore expresses internal model sensitivity, not probability, a coverage level, observed prediction error or external validation.

Medical boundary: Separately, neither the band nor the paid point value predicts an individual death date or provides medical advice, diagnosis or treatment.
