Hahahaaa, this happens to me too, though I haven't thought about it this way.

I don't think I fall under any of the four types of writers you mentioned, since I'm a work from home mom.

But when I have a good night and manage to wake up at a decent hour, before my son, I write a decent amount with the hunger blowing on my neck.

And if I'm really lucky, once I fill my belly, I may write a bit more, taking advance of the energy boost that I typically associate with being well fed :D
