Backtested 67.7% on 14,777 walk-forward games, but the market beats it on real closing lines (66.95% vs 67.70%, ROI −6.2% to −8.9%) — informational, not a signal. Original claim covered 14,777 walk-forward games. Stratification suggests mid-major lines may be sloppier (hypothesis: edge concentrates in MAC/Sun Belt/American), but real ROI requires odds data we're capturing forward via the EV scanner.
