In one of Dota2's recent patches, Valve has added a new feature called "Performance Index" visible in your own in-game profile. It is not clear how it works. Is there any information available, what "performance" it monitors? Does it rely on `K/D`, `K/D/A`, `Gold per minutes`, `Experience per minute`, or all of them? ![Example for Performance Index][1] [1]: https://i.sstatic.net/F9eqH.jpg
