Thanks for the tips on how to produce a recording Thomas. I've setup a folder called '2011 WC' where the audio and video files can be uploaded. http://arimaa.com/arimaa/ftp/

Thanks for creating the 2011 Wiki page Fritzlein -- the player list was a big help in this 33 player tournament!! In case anyone isn't familiar with the Arimaa Wiki, here's a brief overview of the information for the World Championship: The main page has a list of the participants and the standings at the bottom sorted by pre-tournament ranking. http://arimaa.com/arimaa/mwiki/index.php/2011_World_Championship Every round will have its own page with standings sorted by number of wins, ties broken first by the Strength of Schedule formula then by pre-tournament rating. http://arimaa.com/arimaa/mwiki/index.php/2011_Open_Classic_Round_1 By the way, has anyone calculated the value of the Strength of Schedule variable yet? I can calculate it also, but I'd like to verify that I'm matching the official number (which I did not do last year!)

What is the Strength of Schedule formula? I'd kinda assumed apparently incorrectly that it was based solely on opponent's wins, but that would imply that everyone would have 0 at this point, instead of .5 or .03 (Can't even see where that number came from, although the .5 might be from according both players half a point until they play, which would make the standings be the standings after pairings as opposed to after the end of the previous round, which is reasonable, provided that the standings at the end of each round are also visible somewhere, although I guess that would make sense to be at the end of the prior round's page... That stream kinda got away from me, so allow me to repeat the important part, a request for the formula used in determining Strength of Schedule.

| Thanks for changing that Joel. It makes the list much easier to match up with the list in the gameroom. When I had entered the pairings the game times had not been finalized yet.

I've setup the tournament to use the Swiss algorithm which allows dropping out and late joins. I did this in case a player drops out of the tournament before it is over. Chances of this are higher when you have more players. It uses a slightly different SoS which was discussed in a thread that I can't seem to find right now. I hope this should be OK.

It seems the population number is more appropriate, but I'll wager the "stdev" function returns the sample number. No big deal either way, because a small change in the F factor is extremely unlikely to change the order of the SoS, even if it changes everyone's value of SoS slightly. The important point is that games against nearly-equal opponents count way more than games against opponents that are significantly above or below, which is ensured by either factor of F.

| I updated my program yesterday to use 3.746 as the F factor. I agree with you that it probably doesn't matter either way but I'd like to confirm with Omar for consistency purposes (rounding to 3 digits should be close enough?)

There was a request in the chatroom to show the WHR ratings for both players in the same row. The Table of Contents will now be updated each round with WHR for each player. I'll show pre-tournament WHR every round rather than try to update it every week with the most recent rating. http://arimaa.com/arimaa/mwiki/index.php/2011_Open_Classic_Round_1

Thanks! Starting WHR makes the most sense for this tournament.
