Let us explain how matchmaking works in Team Event. Each Team Event lasts for 3 days.
On the first day, your opponents will be drawn from the basic player pools.
Bronze - Silver level pool
Silver - Gold level pool
Gold - Gold level pool
Diamond - Diamond level pool
Black - Diamond level pool
You and other players will then race 10 times against random opponents. You receive 3 points for a win and 1 point for a loss. If you win 6 or more races, your last race (whether you win that last race or not) will be added to the record (opponent*) pool for the second day of the event.
On the second day, you will also race against 10 random opponents from this new record pool, and if you win 6 or more races, your last race will again be added to the pool for the third day of the event. You will receive 6 points for a win and 2 points for a loss.
On the third day there are again 10 races (from your pool + totally random opponents), but you have to win them all to get a special prize. You get 10 points for a win and 3 for a loss.
If there isn't enough race recordings for the second or third day's pool, recordings of the previous day's races will be used.
