That is, presumably, assuming that the Principle of Indifference is correct.
I've got an issue with the PofI though; the problem of identity, or, how do
we decide whether a consciousness in a different branch or time is "mine"?
Is all that is required is that an identical brain-state exist elsewhere or
elsewhen? Then, as you've noted, there is an issue of sequencing. Why assume
a jump must always be forward in time? With no physical continuity between
brain-states, our consciousness might get stuck in an endless loop:

sorts, albeit rather a hellish one; but I suppose we wouldn't "realize" we
