Help with an Elo Ranking Question

Me and my teammate have only played 2v2 matches together but he has a higher elo then me and every game I have the highest total score and most military score and the highest eco score. He is ahead by 13 points and i’m curious if anyone knows the reason?

Elo only cares if it’s a win or a loss.In team-games, your team is assigned a % of winning vs the opponent based on the elo difference team-wise. Both winners earn the same amount of elo as each other, and both losers lose the same amount of elo as each other.
