As mentioned in the IB, best 3 of 4 will be used to determine the final winner.

Here are the changes since last year
1) No weightages to individual contests
2) Bonus points will be applicable for early finishers.
3) Scores will be normalized. Top player gets 1000, others' normalized score will be computed proportionately based on their score. (Unlike LMI ratings, ranks will not play a role)

Hope that addresses all the issues.
