Extension of the curves in Figure 2 by two different models.

  End value

Dn / D1 Logistic model Saturation growth model
D 6 114 98
D 4 107 97
D 3 114 109
D 2 63 105

Logistic model y = a / (1 + b * e exp(-c*x)).

Saturation growth model y = a * x / (x − b).

a, b and c = positive coefficients.

The saturation model is more realistic.
