Apparently the first eight moves took 6 hours (http://chessbase.com/newsdetail.asp?newsid=5241)

Personally I think the report is a bit big on the numbers. 6 hours for the first 8 moves and then 8 for the rest? That means that most games didnt reach 20, which I doubt (or they must have been facing Micawber's 1.e4) in particular as the time per move will go up (thinking time will go up, due to position and tiredness, plus extra walking distance).
And 500 meters for 360 boards?


Still I think the Dutchies have a better claim and it is more fun. Can you imagine having to play 6 hours for your first 8 moves (and you will have to move immediately when he arrives)?

Ok thx, so there was a difference after all.
But does it influence the walking distance?
It seems to me that the actual hours you play and the average length of the games and the average time standing still at a board are of great influence as well. 
Suppose I agree to play a thousend opponents and everyone is so impressed that he resigns after I play 1.e4! Evidently I wont have to walk that far, unless the organizer have made the distance between any two players 1 km

For instance Rosendaal played 30 hours against 720 players, so he must have walked a large distance as well.
And if a large number of games has ended, you can take a short-cut, depend on the way the playing arena is layed out, and the participants are distributed.
Does anybody know how long Bohm had to play to achieve his record?

Georgiev 14,5 hours 360 games=  2,4 min per game.
Rosendaal 30 hours 730 games =  2,5 min per game.

I thought susanpolgar had the record from doing a huge simul in mexico that most people claim was faked.
