Team points in ranked

Meaning, your total team value when you see which team is favored. How is this number determined? I figured it was just the total of everyone’s individual skill value added together, but the last several 2v2 Gnasher matches I’ve been in, both teams will be around 30,000 and I’ll just be at around 1500. Is it saying that I’m really playing with someone who’s 28500 points all by himself, or is there some sort of base value, and individuals are added onto that?
