Win probabilities reflect full-field Monte Carlo simulations. A 10% pWin means roughly 1-in-10 chance of winning — higher than most bettors realize for a 36-car field where the average driver has ~2.8% odds. Top 5 and Top 10 percentages similarly reflect simulated outcomes, not historical averages. Learn how the model works.
