I'm really starting to hate arena. Fast games is fun, but the pairing is ridiculous.
The person who won the last Arena I was in had twelve games in a row with players who were lower rated then them. I checked his game archive.
I recall Danny Rensch explaining how Arenas work differently than standard tournaments, stating that it's not about how many wins you get, it's about how many wins you get in a row. But realistically, when you could get paired with *anyone* in the Arena, from 400-2000, it's really about who you get paired with.
I wondered for a while why higher rated players weren't winning more tournaments. i figure they were statistically more likely to come across lowered rated players, because there were many more lower rated players than higher rated players. But it doesn't matter. As soon as you get paired with anyone close to your rating or above, and you lose, your streak is over and you don't get as many points. So while these higher rated players were probably winning quite a few games, the medals wound up going to those middle rated players who coincidentally were paired with lower rated players consistently.
Arena sucks!
For a 10|0 or 15|10 Swiss tournament, you might have to wait several minutes between rounds for the next game.
