All you need is not a huge perfect ranking of all active players to make such stats, it's the most accurate way to describe a player's chances to beat another player. we both know you and me that starcraft 2 is a not a transitive game so basically basing your whole analysis on ELO which is a ranking that pretty much compares the wins and loses of a player vs everyone against the wins and loses of the other player doesn't make a lot of sense to me. we can further develop by PMs if you want. i'm sorry i was rude at first. ps: why not use R instead of python, i find python terrible. could you also please detail the probability of player A to beat player B based on their ELOs, i'm interested anyways.
And statistically improbable things happen. Not sure what your qxc example was suppose to show. Are you saying there is a mathematical model which would have predicted that qxc would AK IM?
Of course, ELO has its flaws. Some does any statistical model when so many variables are involved. But to say ELO only applies to chess and not SC2 is just strange. Since the ladder is basically a modified ELO.

Yeah, I would be happy to get suggestions, but you don't offer very specific ones. Yet, anyway.
As a statistician you surely know that improbable events happen all the time. (See that famous Feynman quote that I'm sure you've heard.)
The blog post was aimed at the hordes of people asking "where do you get these numbers?" — people with high school maths knowledge at best. Not working mathematicians. My hypothetical assumption that Elo is a perfect predictor (and I know very well it is not) was mean to clarify readers that that is where the potential problems lie, and that everything after is genuine (up to a point, such as independence between games).
I know Elo is hardly perfect, but it's what we have at the moment, for better or worse. I'm sorry I couldn't offer you something mindblowing. This is a three weeks old project based on my free time only. People (mostly) seem to enjoy it for what it is, and if I or someone else can make it into something better, then all the more power to us.
I don't know R and Python is awesome. :D
(Apology accepted. Suggest we keep this to PMs or the blog post from now on.)

I am not sure whether you are desperately trying to pose as a competent person in order to give authority to your argument or if you are the competent person who is absolute least capable of expressing himself that I have ever met in my life. Except I am quite sure it's the first.  Chill, nobody cares about the little skirmishes in LR threads. Live and let live.

He does this all the time. constantly blows huge leads

Is it just me or does Ret always look like a platinum level player?

Wow. Ret plays like he has completely given up on trying at this game.
|
Poor games from Ret, really poor. Hope he can pick it up in the lower bracket!
