In the above calculation I forgot to mention that for simplicity I assumed that the experiment is such that one would normally have a 50% chance of survival. If this value is different, the values above would be different, but the fact of agreement would be the same (although there would also be the difficulty that a chance other than 50% is not easy to reconcile with a many-worlds theory anyway.)
