How does this point system work?
From what I understand, winning is just a part of the equation. A decent portion is your performance within the match, how well you are doing against people of different mmr, so if you are scoring well against those higher than you in mmr, you gain more points. There seem to be so many factors calculated in the background about what chance you have of winning based on who you’re matched against, like a bunch of solos against a premade, so if the solos do better than expected, there might be points or much more leniency of not losing any points if you lose if it was a close match, etc. There’s a person in the top 50 (stephane zan.1754/Fadded Moon) who has about 100 more losses than wins. I believe I’ve seen Fadded Moon as a thief, so he/she’s probably very good at having a great score of backcaps and killing lots of higher mmr players that those are bringing up the score a lot more than losses bringing it down. If you look at the leaderboards, it’s based on score, not W/L.
It’s based on your team’s endscore and on how the outcome of the match was predicted.
Here’s the wiki-entry about it:

And here it is put into an easy-to-read table, which someone else posted in another thread:
Thank you for that information. Table is very helpful. Wow , I guess this new matchmaking system and point system encourages you to PvP in teams rather than solo-q.
