W(t) = W_max × (1 - e^(-K(t - t0)))^b

The standard model for indeterminate growers. Growth is fast while small and asymptotes toward a maximum the organism never quite reaches — which is why a well-fed creature does not grow without bound, and why the last increment of size is the most expensive one it will ever buy.
