S&P+ results just show how hard making predictions can be

The link below contains S&P+ results (against the spread, and vs. the over/under), by week, for the 2018 season.

The S&P+ model is pretty damned advanced, and it was built by people who know an awful lot about football. And, still, its predictions are correct just over half of the time.

In its best week, the model went 34-20 (63% winning percentage). If you bet $100 on all 54 games, you'd make a profit of about 26% ($1400).

In its worst week, the model went 27-33-1 (45% winning percentage). If you bet $100 on all 61 games, you'd lose $600 (-10% for the week).

I'm surprised there aren't more dramatic peaks & valleys on a week-to-week basis. Regardless, my top take-away is that trying to predict college football results is a fool's errand.
