There is an algorithm on the ratings of the people you beat and who beat you. The fewer games means nothing, rather.... 3lt might have lost an extra game, but he had a 6 game win streak to your 4.
This article will elaborate on the tie break process: https://support.chess.com/customer/portal/articles/1444840-what-happens-when-there-is-a-tied-score-and-what-is-the-tie-break-
Not sure if this is the same process used for live chess, but i am sure there is some sort of algorithm going on.
Just out of curiosity, anybody know why I was placed fourth here rather than third? We are tied for points, I'm higher rated and lost fewer games. What else is being considered that is more important than these three things?
