I don’t think so. On most branches the probability (or the indeterminacy) comes from the fact that most of the 1p(p) histories will be algorithmically incompressible, and thus highly non predictable, and behave, for n great, as random sequence. “W or M” will be the only always correct prediction, and P = 1/2 will match well the ignorance in a set with a measure converging to the Gaussian. Most 1p or 1pp will just predict white noise, like we predict that a sheaf of light get divided by two when going through an half silvered mirror. The worlds/histories departing from the normal distribution get infinitesimally rare in the limit (and Dital Mechanism explains why we have to consider that limit, mainly the invariance of the first person experience for the delays of reconstitution in the arithmetical Universal Dovetailer. > there is no 3p view (God's-eye-view) to contradict them.

With mechanism, the quantum Many-Worlds (or any physics) has to be explained by the single-body (or single population of bodies) duplication/multiplication occurring (virtually, arithmetically) in arithmetic. If interested I can explain more. A lot of people miss that the notion of computation (i.e. the notion of universal machine and their executions) is a purely arithmetical notion. Gödel is the first to have shown this, but he did not realise what he as doing because he missed, in 1931, the Church Turing thesis, as he explained himself. Gödel will accept it later when reading Turing.
