According what you have been pointing out all the weekend, you dont have the
complete pgn file of the Tournament. If this information is correct,  then you
table is not valid, because you are not considering all the games.

Second, what is the sense of putting an initial value of 2400? Why not 2000 or
2800? I do not find logic to say an Elo of XXXX based on an incomplete pgn file
and an initial elo that you put arbitrarily.


>It is really that hard to understand?

I return this question. Is it really impossible to understand that your
estimation is useless? You cannot sell a thing that it is incomplete and it has
been manipulated.

I dont know, a realistic rating is not based on any assumption that you think it
is true for yourself.

As 2 + 2 = 4, How do you put 2400 as the initial value? Really interesting how
you collapse under a sea of ambiguities.

Arturo.

PD: Accusing me of being other person says a lot about your person. Just a
comment.
