Is one tournament enough to decide the best basketball algorithm?
It's better to be lucky than good! Besides, when was the last time your office held a cross validation pool?
Can I update my predictions after the tournament starts?
No changes are permitted once the tournament begins.
How is the leaderboard going to work when the event being scored hasn't yet happened?
You won't submit after the tournament starts. We'll update the solution file as the games occur, which will cause the ranks on the leaderboard to change.
Why don't predictions in later rounds count for more?
While it is possible to weight the later games, we chose to keep scoring simple and count all games equally. Any weights we pick would be mostly arbitrary (how many first-round games is a championship game worth?). Also, weighting any game increases the role that luck plays in determining a winner. We've also structured the competition so that people can still be in the running even if there are early-round upsets.
