*An individual's tourist factor is defined as the probability that this person would perform better than tourist in a Codeforces round, as predicted by the Elo Rating System.

**Contestants with question marks in their country have not told us which country you wish to represent, and this is my best guess based on your Codeforces profile.


Does CF Rating Predict Hacker Cup Performance?

Here's a graph of the finalists' rating vs. their Round 3 place:

So yes, it's a good predictor, but it certainly doesn't explain everything; it's not out of the question that any competitor could have an unusually good or bad contest, as you would expect.


Post-Contest Livestream (on Facebook)

Yep, be sure not to miss all the excitement in the post-contest livestream, during which Zef and I reveal the final scoreboard! Get excited--I'll see you Saturday!
