It is a mystery that Marchal can not get it through his head that
copying a person means there are now 2 identical first person
experiences because YOU HAS BEEN DUPLICATED, and the 2 will remain
identical until one sees something that the other has not.
Which is the time he has to confirmed his previous prediction.

If "you" predicted that "you" will see Washington and "you" does see
Washington then the prediction that there was a 100% chance that
"you" will see Washington was correct and it doesn't matter how many
people who also lay claim to the title "you" don't see Washington.
The same can be said for a coin throwing. the guy who predict "tail",
and got "tail" can says that his prediction was correct. So if your
argument can be used against the FPI, it works for MWI and for coin
throwing. You are mocking any notion of probability.

The diary is useless because the diary was written by "you" and
contains predictions about the further adventures of "you", but now
there are 2 (or more) people with the title "you" ...
..., but now there are 2 (or more) people IN THE THIRD PERSON POV, but
the question concern the FIRST PERSON POV. And in Helsinki, you knew
this in advance. You know that you will survive and experience being
in only one place.
... and no way to determine which one the diary was referring to.
False. It is very easy. In both city the diary is the one you have
with where you have found to be, and it is the diary containing the
prediction written in Helsinki.
And the diary is useless because good predictions have no more to do
with identity or a sense of self than bad predictions.
Exactly. So if you wrote W & M, both copies know that the prediction
is wrong. With "W v M", both copies know that the prediction was
correct.
You continue to ignore that the question concerns the 1-you, as seen
by the 1-you, and not any 3-view of the situation.
