Proof, not promises

The WarriorSim™ track record

Before every slate locks, StatWarrior archives what it published and builds its own WarriorSim lineups. The next morning the leagues' official box scores grade all of it: projections against real points, and the pre-lock lineups against a modeled field and the perfect-hindsight lineup. Nothing is rebuilt after the fact.

Projection error is the average absolute difference between projected and actual points. Pre-lock builds are a subset of all graded slates. Any field comparisons in the live scorecard use a modeled field, not a real contest. A dash means the metric is unavailable. Model estimates and past results are not guarantees.

Day by day

How the grading works

  • Archive. Every slate on the site is saved as last published before its lock: projections, projected ownership, salaries.
  • Pre-lock builds. About 35 minutes before lock (and once more earlier), StatWarrior builds 20 WarriorSim lineups and one max-projection lineup for itself with default settings, and stores them. These are the lineups graded here. From October 25, 2026 they come from the current WarriorSim engine (Tournaments mode: top-1% coverage); earlier days show the previous engine.
  • Real points. After the games, every player's DraftKings and FanDuel points are computed from official box scores with each site's scoring and bonuses: NBA and NHL (league feeds) the next morning, MLB (MLB's stats feed) the next morning, NFL players and team defenses (nflverse) once the week's stats publish, usually within two days.
  • Projection grade. Average error, bias and correlation between projected and actual points, plus how often players beat their P90 or fell under their P10 (the ranges are right when those sit near 10%).
  • Lineup grade. Each pre-lock lineup's real points, the perfect-hindsight lineup the slate allowed, and the finish of each lineup in a 1,000-entry field drawn from the slate's projected ownership and scored with the same real points. That field is a model on real results, not a real contest; real-contest grading comes from uploaded standings files.

Model estimates and past results are not guarantees of future results. StatWarrior is a research tool, not a sportsbook or a DFS operator.
