Why is the Bonus Point not included on the global leaderboard?
The Bonus Point applies only to the contest within the pools and not to the global leaderboard. This is because it is a competitive point and it would be unfair to compare players from different pools if it were included. E.g., in a pool of 8 players the BP is easier to win than in a pool of 14, and in a pool of useless players it's easier for a good player to win. The only fair way to compare players in a global sense is to exclude it.
