Hello everyone,
today, we’re going to talk about skill MM. Again. I must admit, this topic is not exactly a favourite of mine. But I know someone, who knows a lot about statistics. That’s right, Edrard, the creator of the first efficiency rating – so he really understands this stuff. I asked him on his opinion and here’s what he had to say on the matter (translated from Russian of course). Enjoy!

My personal opinion is, that the skill MM is definitely not needed. For one: there are far fewer good players than bad players, in a ratio of somewhere around 1 to 10 and really good players roughly 1 to 100. When it comes to the range from bad up to above average players, the distribution of such players is linear, therefore every time you enter a battle, according to the probability theory, you’ll have basically roughly the same teams. Of course, there is a chance that you will have a team full of bad players and the opponent will have a team full of above average players, but if you take an infinite number of battles, then the amount of such battles will be equal to the kind where you have the above average team and the opponent has noobs. In general, the distribution is always the same. Since the amount of good players is still large enough, the probability of having at least one on your team to be quite high, but let’s have a look at an example.
