First off. I have _all_ the game that Diep played. The table is valid.

I looked up all participants in the SSDF, or the WBEC. I averaged out the rating
and came out at 2430. I simply rounded down to 2400.

How has it been manipulated? The games are in black and white, and can be viewed
on an official website. How can one manipulate that?

I have _two_ lists to base the start value from. I am assuming you can add and
then average numbers correct?

Try it, numbers are great :)

How have I collapsed? I have stated the same thing from the very beginning. It
is you that just can't get it through your thick head that there was an actual
formula here.

As I asked before. Would you like me to adjust the start value to 2500 just to
ease your simple mind? This is pointless you argue with you over. You will never
get it.

And your arguement here is only making you look like a complete idiot. You quote
previous tournaments, I give you numbers based on those events. You argue those
numbers. I give you numbers based on the just past IPCCC and what a surprise you
argue those as well.

And as for accusing you of being another person is just what you are looking
like. I can provide all the data in the world to you, and it will _never_ be
good enough because of your personal view about the strength of Diep. I could
take every single game it has played and come up with an average elo, and you
would argue the start value only to make Diep look better.

Isn't this what all the fuss is about? That the start value makes Diep's
performance look bad? Well guess what.. IT WAS! Give Diep 100 elo more. Now it
is 2497. Happy now? Maybe 2597? Even better? 2697... use some damn common sense
here and do the math. It is _not_ off base.

Based on the results at CCT7 and IPCCC2005, I could state the same thing about
Ikarus. This conversation isn't about anything but the _performance_ of Diep.
Not where it finished, not the moon and the stars. Just it's performance.
