Ah, I was thinking more of a huge (infinite?) set of simulators, each running for some finite number of ticks. Then the subjective probability of being in program number n is related to the proportion of simulators that run program n for long enough to reach a feasible world for you to be in. So, sure, program A gets more ticks than B in the original scheduler, but I think the determining factor is how many simulators go on to run B at all.

Ooooooh. No, I guess the model we're using here (that is, the fanfic in question) is that somewhere down the levels there is a single simulator running a "program of all possible programs".

Although, I wonder if we can then just say the bottom level is Tegmark's Level 4 Multiverse and get rid of any actual machine or such at the lowest level. :)

Tegmark's Level 4 doesn't answer the question of how much weight each experience has. It's a similar problem to asking where do the Born probabilities come from.

Well, it doesn't seem to me that it'd be any more confusing than "turing machine running the program of all programs" as far as difficulty of reasoning about weights.
