As you can see, as in previous IOI demonstrated by the blogs above, even though there is a clear trend, there's too much variation in the data to get something out of. However, here are some interesting facts: - Out of the people that got gold, the one with the lowest rating, has a lower rating than the person that has the lowest rating out of the silver medals. - Only 30.58% of the participants have a linked CF account(!) -
