Whatever else it may be, by the rules of this discussion, a decision is a type of physical process. So if it is possible for the decisions of a superintelligence in one branch of a superposition to affect the recoherence time of the whole superposition, then logically it must be possible for physical events in one branch of a superposition to have this effect, because these “decisions” are just a type of physical event.
So the key idea that needs investigating is the whole idea of events, occurring “in one branch”, which affect the recoherence time of the whole. This might allow us to temporarily sidestep the, uh, issues surrounding Wallace’s “derivation” of the Born rule from quantum decision theory (which is the reverse of how everyone outside the Deutsch-Wallace school of thought sees it). If reducing the time to recoherence is the objective, one should first try to understand what “recoherence acceleration” looks like. You could look at some of the models of recoherence that you just posted, find out the parametric dependency of the time to recoherence (that is, find out which parameters or physical quantities it depends upon), and then think about what sort of processes, inside or outside the system, could control those parameters.
I also think the derivation from decision theory is really circular (which I think is the same as “reverse”), which is unacceptable. I say “circular” because we don’t know very much about either the Born rule or decision theory. ;)
I’ll look closer at your comment later. I’d like to send you a much longer essay. (I received your email and want to respond to it but have lacked the necessary psychological motivation. I really, really appreciated how you kept your eye on the “save the world” ball unlike everyone else.)

Thanks for restating the key question in a very clear way.
