csgo has this system Trust Factor

What can I do to improve my Trust Factor?

The only way to improve your Trust Factor is to be a positive member of the CS:GO and Steam community. Trust Factor matchmaking will continue to be adjusted, but all players have to do to improve their matchmaking experience is continue playing CS:GO and other Steam games legitimately. The more a user plays, the more information the system has and the easier it will be for the system to determine who they should be matched with.

Csgo match with different people based on what and how many games you play on steam and you tell me there is no system for 50% winrate
