Sorry, now I have no idea what we’re talking about. If your experiment involves killing yourself after seeing the wrong string, this is close to the standard quantum suicide.
If not, I would have to see the probabilities to understand. My analysis is like this: P(I observe string S | MWI) = P(I observe string S | Copenhagen) = 2^-30, regardless of whether the string S is specified beforehand or not. MWI doesn’t mean that my next Everett branch must be S because I say so.
You have to specify a particular string to look for before you do the experiment.
