Cortana now has a 20-12 record on the year.
For comparison, Las Vegas favorites are 18-14 overall and Nate Silver’s ELO model is 19-13. Considering that the engine is just predicting winners and not results against the spread, 20-12 is just an okay record.
In the Week 2 games in which Cortana and Vegas disagreed (Baltimore-Pittsburgh, Miami-Buffalo, New York-Arizona), Cortana went 2-1 and Vegas went 1-2. The Microsoft engine had the Bills as a 62.9% favorite while Vegas initially had the Dolphins as the favorite. Buffalo won 29-10.
