I think the whole number of the lobby is the point rating of your car thing is false. tho it could just be that the servers are totally lagging, but ive been in 1651 cars in a 1650 lobby. 1664 in 1663, etc. Had ratings go up every time i re-enter the lobby. things like that. so theres alot more to it then just guessing…
It's actually different for me, I had cars ranging from 1643 to 1651 and they all got put in the same lobby. Refreshed the game and their ratings changed every single time I did it. Did the same thing in d class where downing to 1640ish still put me in maxed lobbys.
