Note on the model - when I"ve attempted to use it before, I've gotten the following. As you can see, it isn't perfect, but it's pretty damned good.

Super Bowl 49 - Seattle 28 New England 24
Super Bowl 50 - Carolina 28 Denver 23
Super Bowl 51 - New England 31 Atlanta 27
Super Bowl 52 - Eagles in a romp over Patriots (note: the numbers I got weren't close to the final score)

I haven't used it since the Covid pandemic because I've been too busy otherwise.
