Details
Equation:
rT = \frac{C}{1 + e^{k1 + k2 * T}}
and
rT = \frac{C}{1 + e^{k1 + k2 * (2 * Topt - T)}}
where rT is the development rate, T the temperature, Topt the optimum temperature, k1 and k2 constants. "[...] the relationship [is] inverted when the temperature is above an optimum [...] T = 2 * Topt - T for T >= Topt." Stinner et al. 1974.
