We all know the game quality indicator is the single most important number in all of FAF, for the tears of a thousand nerds are summoned forth if it is ever too low.

So how is the calculation produced, exactly? What is the algorithm it uses?

I ask because it has been my experience that it is accurate in 1v1s and most team games, but wildly inaccurate in games with high rating differences, such a 5v5 team games featuring players rated -100 alongside players rated 1700 - a different of 1800 points.

So what is the exact formula? Is it possible that it inflates the value of points at the higher end of the scale? Sort of like a cartesian distortion...

Thoughts?
