See my reply to TheAncientGeek, I think it covers most of my thoughts on this matter. I don’t think that your second paragraph captures the difference between RQM and MWI—the probabilities seem to be just as arbitrary in RQM as they are in any other interpretation. RQM gets some points by saying “Of course it’s partially arbitrary, they’re just maps people made that overfit to reality!”, but it then fails to explain exactly which parts are overfitting, or where/if we would expect this process to go wrong.
