Details

Equation: c(rT ~ C / (1 + exp(k1 + k2 * T)), rT ~ C / (1 + exp(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.
