No, pi would contain only an infinitesimal proportion of the
computations underpinning any given physical reality, since there are
infinitely many transcendental numbers, as well as all the other

So if two computers implement Monday and Tuesday in isolation from
each other, i.e. purely by chance, there *won't* be subjective
continuity between them, while if two similar computers implement
Monday and Tuesday in a similar way, except the programmer set up
Tuesday having knowledge of Monday, there *will* be subjective
continuity between them? How is this discrepancy possible, if mental
states supervene on physical states?

You have to explain how the computations know they are causally
connected, and not just accidentally connected. And in any case, the
parts of any random system, such as atoms in a gas jostling each
other, are causally connected.
