Dear Realpenguin,

I commend you on your use of high-level statistics. I find myself looking at the graphs over and over again in case I missed something profound. I will present these findings to my grad school friends for further investigation.

Nonetheless, I must bring up a point which may destroy your analysis.

It is incorrect to say that Flash and Jaedong have a 0% winrate against Bisu last night.

Here, winrate, by definition, equals

(# games won against Bisu) / (# games played against Bisu).

Now, if the denominator (i.e. # games played against bisu) equals zero, you have a meaningless statistic. Ergo, the stats for Flash and Jaedong are UNDEFINED, not zero.

Please don't shit on Flash and Jaedong by using false statistics.

I must add, however, that if you wanted to keep the misleading edge of your article while preserving the persuasiveness of statistics, I urge you to change "winrate" to "win count", so that you may use the following:

Games won against bisu last night
Guemchi: 1
Flash: 0
Jaedong: 0

As you can see, it's very similar to your analysis with "number of losses". Very misleading yet correct -- a perfect use of statistics.


Sincerely,

Your Fellow Statistician
