If Many Worlds is correct then the universe and all the observers in it
splits at least  5.4* 10^44 times a second (probably more, possibly
infinitely more) and so the number of observers who see various things
constantly changes.

You keep talking about "probability" but what does that word really mean?
If Many Worlds is the correct interpretation of quantum mechanics then
probability is not a part of the intrinsic nature of reality, probability
would just be a measure of our ignorance. Probability allows us to make the
best use of the limited information that we do have and find the best
strategy to maximize our gains from a series of bets. But the sum total of
reality (aka, the Multiverse) does not need probability because it is
completely deterministic, at least if Many Worlds is true.
