multiple worlds require no additions to the length of the theory if it was formally expressed, whereas a 'deleting worlds' function is additional.

Is there a formal expression of the theory of measurement (in a universally agreed upon language) where this can be demonstrated?

Not a clue. But in this particular case, the argument is that the theory without mutliple worlds is precisely the multi-worlds theory with an extra postulate, so it's certainly more complicated.

It would really help if some people who knew about the relevant parts of the Sequences lurked around to aid the confused!
