For the last five years, Davidson College students have consistently predicted the outcome of the men’s NCAA college basketball tournament with a great deal of accuracy.

In short, their guess is better than yours. Not only that, they continue to fine-tune their prediction methods, and this year there’s added incentive to strive for perfection.

Tim Chartier, associate professor in the department of mathematics and computer science, and his students have out-guessed millions of people using math. Predicting the outcome perfectly has never happened, but it appears mathematicians have an upper hand.

In 2009, their best bracket beat 97 percent of 4 million entries to ESPN’s annual online contest. In 2010, their best bracket beat 99 percent of 5 million entries. In 2013, their best bracket beat more than 96 percent of 8 million bracket entries. Other years, ratings have slumped to below 90 percent, but not one sports analyst did better than their best entry, said Chartier.

In 2010 Alex Herman, an autistic teenager from Illinois, claimed to have a guessed perfectly through the first two rounds and predicted Purdue to win – but Duke won that year. The odds of getting that far were 13 million to 1.

Last year, none of the 8.5 million brackets submitted to ESPN had a perfect bracket after the first round, said Chartier. Everyone got at least one wrong in the 32 games played.
