I think Russell has already given his own views on this.

I basically agree (except that the coin toss needs to be a quantum event for
Everett), but see below.

Fine, but you can do the same for the Everett higher universe (sometimes
called multiverse) as well - the information cost of the repetitive element
still has to be added. (Effectively this is an example of '>n' case I
mentioned before, where cancelling through occurs; Everett splittings are in
the '<n' region because they are essential for SAS's in Everett's scheme.)
(Incidentally this is one area which illustrates one of the potential
pitfalls of using the TM-computational approach as a model: the 'loop-back'
('return to start') command implies an immediate maximal repetitive factor,
with little information cost, which could distort measure calculations. I
prefer a more general informational approach.)
