- Elo and Cortana have made their picks for Week 13.
- Cortana leads the overall race, correctly picking 68% of the games this season.
- The computers disagree on two games this week.
Week 13 of the NFL season is here, and Cortana is back to make picks in a head-to-head showdown with Elo.
We looked at two popular systems used to pick NFL games: Cortana, Microsoft's digital assistant, and Elo, the modeling system used by Nate Silver's data-journalism site, FiveThirtyEight.
In both cases, the computers are picking outright winners and not against the spread. However, each gives a likelihood that a team will win - which, in theory, could help measure the strength of certain lines.
Cortana is off to a strong start this season, correctly picking 68% of the games overall, including an 11-4 record in Week 12. Elo has nailed 63% overall and 12-3 last week.
Here are the picks for Week 13, with each team's percent chance of winning in parentheses. Point spreads are for reference, via Vegas Insider as of Thursday morning.
