So I'm in a 5 person tournament, one game at a time per opponent.  That's 20 games total, with 10 at the start.  1 game has been completed.  The completion percentage read 9%, which is 1/11 (1 complete, 11 started).  Shouldn't it read 5%?  Thanks.

Edit:  For clarity, and the following:

The tournament in question is "Fast One" by the way. :)

 

My guess is that it's a 5->2  tournament. In the first round It's 4 games for each of the 5 players, so that's 10 games. Then there is an additional 1 game between the top 2 players for a total of 11 games.

4 games for each of the 5 players...

4 x 5 = 20!

mmmmmmaybe it figures how "far along" the games are based on an "average" number of moves. 

correction:

4 x 5 = 20

20/2 = 10  (because each game is played by two players)

Actually I had a look at the tourney in question and there are twenty games going on: Each player is playing 8 games.
