Suppose I exist in universe A and I exist in universe B. Then the
contribution these two universes make to the overall "probability I feel
the way I do" is p(A) + p(B). If universe C is another universe that
happens to be identical to A joined to B somehow, then I exist in C.
The measure of C may or may not be related in a simple way to the
measures of A and B. (I am not making any assumptions here about how
measures are assigned to universes, in particular I am not assuming the
universal distribution.) So p(C) gets added to the mix.

I don't see anything contradictory in this.

I agree that I exist in the counting universe. The counting universe
would have to have low measure for this model to be true. (Unless I
am actually living in the counting universe.)

I think you agree that you exist in the counting universe. However I
think you give low measure to the places in the counting universe where
you exist because they are so small compared to the universe as a whole.
Is that right?

I think Jacques does not agree that he exists in the counting universe.
He wants to see a "process", not a "pattern". It is not clear whether
a process can be fully represented as a pattern.
