Day 1&2: Round 1
4 attempts per day, each attempt is 5 races
If you get 3+ wins in one of your attempts, you qualify for "Group A" in round 2, otherwise "Group B"
Only your attempt with the highest win count matters, so you can lose every single race in 7 of your attempts, and then win 3 of 5 in your last attempt and you'll still qualify for Group A
Day 3&4: Round 2
4 attempts per day, each attempt is 5 races
