SC2 World Ranking, Part 6: Ratios

Part 5: http://www.teamliquid.net/blogs/viewblog.php?id=359812

+ Show Spoiler [Introduction] +

Lately, I've heard lots of discussion about a StarCraft 2 World Ranking based on tournament results. Essentially, the concept is that you assign points for tournament rankings. Unfortunately, no matter how it is done, the ranking will always be subjective. One person may say that the GSL is worth as much as every other tournament combined, whereas another person may say that the GSL is worth about as much as a MLG.

How do I get around this "subjective" problem? Here's my answer: I'll let you choose the values!

That's right, I'm starting a project to create a World Ranking. The cool thing is that you get to choose how many points each victory is worth and more.

Now updated with "Ratios"! Please check the "How to Use" section for more info.

+ Show Spoiler [How to Use] +

The first sheet is known as "Values" and it is the only spreadsheet you should edit. Only edit the highlighted areas!

I have now changed the spreadsheet to work on ratios. First, start with the point ratios. Simply enter the points that you think a 1st place is worth compared to a 2nd place, a 3rd place, a 4th place, etc.

For example, if I enter 1,000 points for 1st place and 500 points for 2nd place, that means 1st place is worth double the amount of points as 2nd place. If another person thinks that 1st place is worth 3 times as much as 2nd place, he/she can put 1st place as 300 points and 2nd place at 100 points. Simple, right?

The section underneath that (highlighted with a darker shade), the one containing 3rd/4th, 5th/6th, etc. are optional. You can choose the values yourself if you want. If you do not, they work using averages (3rd/4th averages the points you gave for 3rd place and 4th place).

Next, enter the tournament ratios. For example, if I enter 10 points for GSL and 4 points for MLG, that means GSL will give out 2.5x as many points as MLG. Use these ratios to gauge relative importance of the tournaments. If you think MLG is worth half as much as GSL, make MLG 5 points and GSL 10 points, and so on.

The points are calculated by multiplying the tournament ratios with the point ratios. If I put 100 points for 1st place and 10 points for GSL, it will multiply the two values and give you 1,000 points for GSL 1st place. Here's another example:

Say I choose these values: 1st place = 1,000 points, 2nd place = 500 points. GSL = 10 points, MLG = 4 points.

GSL 1st = 1,000*10 = 10,000 points
GSL 2nd = 500*10 = 5,000 points
MLG 1st = 1,000*4 = 4,000 points
MLG 2nd = 500*4 = 2,000 points

The "Sort" button will automatically sort the lists in order of points.

The sheet known as "Rankings" has the ultimate ranking which you are looking for.

+ Show Spoiler [Regression] +

One thing that is very popular in point rankings such as this is the concept of regression. Basically, your points degrade over time, meaning that a GSL today is worth more than a GSL one year ago. I completely agree with this idea, so I've included this.

The sheet "Values" has a "Regression Factor" which you can edit. Right now, the spreadsheet only supports simple regression - exponential decay. Here's how the regression model works:

New Point Value = Original Point Value * (Regression Factor)^(# of Days since the Tournament)

The value I prefer is "0.99769217652702". If you use this value, the number of points will be halved after 300 days (so 10,000 points becomes 5,000 points), the number of points will be 25% after 600 days (so 10,000 points becomes 2,500 points), and so on.

You may choose your own value! If you do not wish to use regression (you think a GSL from one year ago is worth exactly the same as a GSL today), then simply use the value "1".

However, this is not completed yet! In fact, I need your help!

+ Show Spoiler [My Progress] +

Part 1: I started this project on Google Spreadsheets and added the three GSL Open Seasons. NesTea topped the rankings with his GSL Open Season win.

Part 2: I added all of the GSL Code S seasons including the World Championship, Super Tournament, and Blizzard Cup. I also moved the project to Microsoft Excel, which is much much faster than Google Spreadsheets. With the addition of more GSL seasons, the GSL king (also known as Mvp) topped the rankings.

Part 3: I added IPL. I changed the spreadsheet into a macro-enabled spreadsheet and protected each sheet except "Values". The addition of IPL allowed Squirtle to break the top ten!

Part 4: I added MLG. MLG gave a lot of points to DongRaeGu and MarineKing, and they rose many places. MC, MMA, and Leenock also rose some places, while NesTea didn't gain any points.

Part 5: I added DreamHack. A high placement in DreamHack allowed Genius to overtake aLive and break into the top 10.

Part 6: I added IEM. Also, I changed the "Values" system to work with ratios rather than point values for each "cluster" of tournaments. Ratios are more flexible in general.

I need lists of tournament rankings. First, I need the name of the tournament, and the date it ended. Then, I need a list of players starting from 1st place until last place. Here's an example:

Finally, here is my own ranking:

+ Show Spoiler +

1. 26,964 Mvp
2. 23,330 DongRaeGu
3. 21,263 MC
4. 19,133 MMA
5. 16,114 NesTea
6. 14,291 MarineKing
7. 9,894 Seed
8. 9,878 Polt
9. 8,024 Leenock
10. 6,939 aLive

MC gained the most points from IEM (he did win that World Championship over PuMa). The addition of the ratio system seems to have shifted the point values slightly.

Honestly, I was going to write something about IEM. However, my mind is only on one person right now...

IPL TAC 3 was a pretty incredible story. Yes, other people have dominated hard, just like TaeJa is dominating right now. However, I don't think anyone else could have pulled off that 23-3 record, 4-kills and all-kills galore. Mvp at his prime still dropped games here and there. DongRaeGu at his prime dropped games here and there (games that he should not have dropped). Even MarineKing, when he all-killed StarTale in the KSL finals, dropped games here and there.

TaeJa does not merely drop games here and there.

Honestly, if the first Bo9 was played and there was a significant break until the next Bo9 (say, the next Bo9 is played next week or so), then Liquid might have won it all. They still almost won it all, even without any break.

I'm not hating on Liquid or anything, but Liquid had a pretty disappointing performance. (Meanwhile, TaeJa had a phenomenal performance.) Since each member of Liquid lost anyway (except for Zenio's win versus LosirA), it might have been better if they dragged out their games as long as possible, giving up chances of victory. Just turtle and use a strategy that you could never hope to succeed with, but have each game take 50+ minutes to finish you off. All for the sake of giving more rest to TaeJa.

That's how big the TaeJa advantage is. The whole team is there to support him, he's the one who's pulling off the kills.

When TaeJa finally got eliminated by Seed and he sat down on the TeamLiquid bench, I wasn't disappointed in him for failing to achieve that 9-kill of IM. There was no regret, no more expectations, nothing left to do but watch.

Job well done, TaeJa.

Question for you: What tournament shall I add next?
