That's why these discussions are not so useful as an argument of

the MWI is correct or not.
I think something along those lines was Sean Carroll's answer to the
points David Albert raised. Unfortunately, it doesn't wash!
Applying the Born rule to the repeated measurement scenario tells you
that the probability of the extreme branches is low; whereas, the idea
that all possible outcomes occur on every trial trivially implies that
the probability of the extreme cases is exactly one. The contradiction
couldn't be more stark, and waffling about infinite universes isn't
going to change that -- the theory gives two, mutually contradictory,
results.

Reading also the other replies in this thread, it seems to me that you
are actually disagreeing with the MWI on the issue of how this
interpretation should work. But then you have a different version of the
MWI that you can then falsify. In the MWI one ends up copies of an
observer who observer the different possible outcomes, but with the
density given by the Born rule, such that in a classical ensemble with
those densities you also would have those same Born rule probabilities.
