No one believes that we ought to measure a region's Dota skill by its worst teams, so why is it that we judge a region's Dota skill by its best teams? A fair and rational way to examine a region's performance in TI 2 is to look at the average of ALL the teams they sent, not just the teams that succeeded / failed.

This post is about the results each region's teams have obtained.

First, the ratings:

14 wins: A+
13 wins: A
12 wins: A-
11 wins: B+
10 wins: B
9 wins: B-
8 wins: C+
7 wins: C
6 wins: C-
5 wins: D+
4 wins: D
3 wins: D-
2 wins: F+
1 win: F
0 wins: F-

China has five teams in TI 2: iG, LGD, DK, Ehome, and TF

Their results rating:

LGD: 14-0, Rating: A+
iG: 13-1, Rating: A
DK: 11-3, Rating: B+
Ehome: 6-8, Rating: C-
TF: 6-8, Rating: C-

NA has two teams in TI 2: coL and EG,

coL: 9-5, Rating: B-
EG: 8-6, Rating: C+

SEA has two teams in TI 2: Zenith and Orange,

Zenith: 8-6, Rating: C+
Orange: 8-6, Rating: C+

Oceania has one team in TI 2: AL

AL: 5-9, Rating: D+

EU has six teams in TI 2: CLG, Na'Vi, mTw, Darer, M5, and Mouz

Na'Vi: 8-6, Rating: C+
CLG: 6-8, Rating: C-
mTw: 3-11, Rating: D-
Darer: 3-11, Rating: D-
M5: 2-12, Rating: F+
Mouz: 2-12, Rating: F+

Averages

China: (14 + 13 + 11 + 6 + 6) / 5 = 10, Rating: B
NA: (9 + 8) / 2 = 8.5, Rating: B-/C+
SEA: (8 + 8) / 2 = 8, Rating: C+
Oceania: 5 = 5, Rating: D+
EU: (8 + 6+ 3+ 3+ 2+ 2) / 6 = 4, Rating: D

Verdict

China >= NA >= SEA > Oceania >= EU

Given the results in the prelims, the first three regions - China, NA, and SEA are within a margin of error of each other. China is slightly ahead on average, but the variance between their teams is higher. NA and SEA teams are slightly behind China on average, but they are all solid performers and have made it into the WB, while two out of five Chinese teams did not.

Seeing that we haven't yet seen the play offs and the standard margin of error, I think it is logical to say that there isn't a big gap between China, NA, and SEA.

Unfortunately, the same is not logical for Oceania and EU. While the variance in EU is quite high and Oceania has just one team, it is obvious that both of these regions are, based on Prelim results, worse than the other three regions. For Oceanians, it is easy to see why - their scene is isolated and have a small population, but for Europeans, excuses are less useful, and another explanation has to be found.

We've gone back and forth about which region is better / worse - but based on results alone, this is the rational way of looking at the TI 2 Prelim region vs. region.

Correct me if I'm wrong but aren't the numbers a bit skewed because teams of one region can lose to teams from the same region? A tournament with 16 Chinese teams would have Chinese teams averaging at C. If I look at WDC 2011, a tournament in which Chinese teams were decidedly stronger than non-Chinese teams, the overall Chinese score would still be low because the number of Chinese losses to Chinese teams far outweighs the number of Chinese wins against foreign teams. So the more teams you have from one region, the harder it is to get a higher score.

#2 the knife cuts both ways - Chinese teams losing to other Chinese teams depreciate their score, but EU teams losing to other EU teams depreciate their score, too. This is not the equivalent of WDC 2011 because it's not a bracket system, so teams aren't punished by lopsided brackets. The average isn't perfect though, I do want to do a region vs. region ratio but it's a lot of work and still doesn't look at differences in groups.

This is an easy way to talk about it. I think it's an okay measure for now.
