This is like: http://en.wikipedia.org/wiki/Sleeping_Beauty_problem

If probability were a property of physics, then it would be the same at the beginning of this period as at the end.

If you teleport 100 times, then your subjective probability of being crushed to death is going to be very small. That number may go up or down depending on what you believe about consciousness, continuity of identity, and magical incantations. But beliefs and probabilities have nothing to do with reality.

Your objection that it isn't really what's going on and we should just
state the facts of the matter is like arguing that I shouldn't care
what happens to me tomorrow because that will just be some guy who
shares my memories and thinks he's me. Literally, this is true: there
is no objective sense in which I can claim to be the "same person" as
my tomorrow self, it's just that evolution has programmed me to think
that way. Nevertheless, the programming is important to me, and I
neither wish to overcome it nor am I able to overcome it, despite
being aware of it. So when I encounter these duplication thought
experiments my question is, How will this situation best fit in with
my (delusional, atavistic, insurmountable) belief that I am one and
only one person travelling through time in the forward direction?
