Original context

    // Twist for 16 strands: Tw = N/10.6 × 16
    static double twist_16_strands(int N) {
        return (static_cast<double>(N) / BASE_PAIRS_PER_TURN) * NUM_STRANDS;
    }

    // Relaxed linking number: Lk₀ = N/10.6
    static double relaxed_linking_number(int N) {
        return static_cast<double>(N) / BASE_PAIRS_PER_TURN;
    }

    // Superhelical density: σ = (Lk - Lk₀)/Lk₀
    static double superhelical_density(double Lk, double Lk0) {
        return (Lk - Lk0) / Lk0;
    }

    // G¹⁶ superhelical density

Relaxed linking number: Lk₀ = N/10.6
