Average rating of the FAF community

[johnie102]

Hey all,

I was just wondering if there is a way to easily calculate the average rating of all people on faf, or just the people that played in the last two weeks? Is there a database of players and ratings that I can check for this?
Would be interesting to see if I'm above or below average...

[eXcalibur]

the average is and will always be a rating of exactly 1500...

It always seems like there are far more under 1.5k though... surprising.

I really doubt this. It's trueskill, not Elo.

Go to Leaderboards -> Global and Matchmaker.

There you have the ratings of all players (or of the ones who recently played, I'm not really sure).

At the time of writing, there are over 4800 players on that leaderboard. I've done a rough estimate, one that is bounded above.

The first 450 players have a rating of 1500 or higher. I've given them a rating of 2300 (which is about the highest at the moment), that'll hugely boost the average up, but only for the ones with a rating > 1500.

The players 451 to 2100 have a rating of between 815 and 1500, I've given them all a rating of 1500. This is a middle zone that will allow me to choose a nice upper bound for the ones with a rating less than 1500. In checking whether the average is more or less than 1500, I can easily omit these players (but I won't).

The players 2100 to 4800 all have a rating of 815 or less, so I've given them a rating of 815, as upper bound.

The average then is (450*2300+1650*1500+2700*815)/4800 ~= 1190. As all input values were upper bounds, the value of 1190 is also an upper bound. The actual average is probably about 800 (if not less).

The claim that the average would be 1500 is already plausible at best if you see that the maximum is far less than 3000 and the minimum is negative. The trueskill rating theoretically ranges from 0 to 3000, but in reality no one will get to 3000.

[ColonelSheppard]

you cann just take the value from the leaderboard lol

[PsychoBoB]

the 1500 mean is calculated over all registered players, right?

but what is with the players which didnt play for a long time? Are they still counted in the elo system?

maybe the period of time for the elo calculation should be only a few month...

[Ze_PilOt]

The average mean is 1500. About 60% of the players are around that value.

Now, remember that the displayed is mean - 3*deviation.
Read the wiki for more info about that.
Right click or a nickname - View statistics to get the real values of your rating.

Ok, thanks guys. Using the calculation of PlasmaWolf with slightly lower averages taken I get an average of ~860. Is there maybe a way I could get a raw textdump of the leaderboards with the ratings? Then I could actually calculate it.

[Ze_PilOt]

Yes but it will be wrong. Rating are two values, not one.
The leaderboard are just a convenient way to display these two values into one by only considering your worst possible performance.
