O'Reilly DFS Stats

How the model has graded against the real Xfinity finish, race by race.

Does the model actually work?

Every driver in every completed race, re-projected and graded against real scoring.

Higher projection → more points

The model’s top-projected tier of drivers averaged 54 actual points vs 37 for the field, across 51 races, a rising staircase means the projections rank drivers right.

Every driver, every race

Each dot is one driver in one race, projected vs. actual (0.45 correlation; the dashed line is a perfect call). Among the cars that finished it rises to 0.45, the 13 wrecks and mechanical DNFs are the off-line dots no model can foresee.
