Details

Equation:

rT = \frac{K}{1 + e^{aa + bb * T}}

where rT is the development rate, T the temperature, K the distance between the upper and lower asymptote of the curve, aa the relative position of the origin of the curve on the abscissa, bb the degree of acceleration of development of the life stage in relation to temperature.
