You might be disturbed by the fact that in experience 2, the "original" remains the

This, in my opinion, illustrates again that we have to use RSSA instead of ASSA.
Suppose the original goes to Mars and the copy stays behind. Then the probability
the original went to Mars is 1.
The question is asked before the guy enter in the box. This is a "step 5" case. The
probability to feel to stay the original is 1/2.
Everybody feels they are the original.
"original" refer to the third person body. By definition it is the one being
copied.
It doesn't really solve the identity problem to assume it is physical continuity. The
"copy" also has physical continuity; and in any even slightly realistic case the
'original' will be destroyed in the process of extracting information, so there will
really be two copies and no 'original'.
The question before he enters the box is, "Will you find yourself on Mars?" To which
he could reply, "What does 'you' refer to?"
The question is about your future subjective feeling as seen from your future first
person perspective.If you assume comp, you know in advance that you will feel entire and
unique,
No, I expect that two someones will feel entire and unique.
either on Earth or on Mars, and you know that you cannot that in advance (or give me the
algorithm).
But all that assumes that 'you' and 'your' have meaningful referents. According to comp
they are no more meaningful than referring to this number 2 and that number 2 and asking
which number 2 counts the moons of Mars.
