I do have some experience with this from Cake, but Cake has the distinct benefit of (usually) knowing what the dequeue rate is, without having to estimate it.  Without that knowledge, I'm not sure it's profitable to guess - except to specifically avoid tail *loss*, which is not at all the same as *marking* the last packet.
