They still involve the whole MWI, just on a smaller scale.
The difference between randomly choosing when scale gets to a certain point and splitting is that splitting isn’t total. There’s still some interference between any two universes no matter how far apart they are. It’s just that when there’s macroscopic differences, the interference is astronomically small.
Random and Splitting.
Though, I just realized that I should just google around and look for papers on the subject.
Collapse interpretation, IIRC Bohmian interpretation, unreal MWI, etc.
