You can deconstruct those supposedly complete sets of plot types further, into just two atoms: rise and fall. The protagonist rises, then falls, but rises again (not necessarily to the same levels, but you get the idea). Or just falls and falls, but ultimately rises.
Meaningless, but so are those "7 types of story archs" taxonomies.
Sure. Another comes from Jim Thompson, who said there was only one kind of story: "Things are not as they seem."
