These actually matter for rating? Thought it was only about rating and ppm compared to other peoples rating and ppm.Your k/d ratio
the rating of the second best player and his rating
About the session, yea the avg ppm is the reason I got minus but might also be affected by the fact that TB was temporarily down during that time and it got back up during the map, the map was 30min but TB only tracked 19mins (just saying don't take it as whine or complaining).
