(a) The Richards solution (in blue) captures the dynamics of a system with secondary nucleation (n₂ = 4) even more accurately than the Hamiltonian solution (in red). (b) The kinetics of fragmenting filament assembly are almost exactly captured by the new c = 3 Richards solution, significantly more accurately than the current standard; the Gompertz solution (in red) and the numerical solution (in black) to the moment equation for fragmenting filament assembly. ε = 0.01.
