Reliability
The same walk-forward accuracy numbers published on the Method page, restated here plainly: how reliable Wal-Bel actually is, not how reliable it sounds.
| Measure | Wal-Bel | Vegas |
|---|---|---|
| Mean absolute error | 10.63 | 9.72 |
| Straight-up winners | 62.5% | 65.4% |
| Against the spread | 48.7% | — |
Read this as a ceiling, not a promise
Against the closing spread, 48.7% is below the 52.4% needed to break even. Straight-up winners and mean absolute error are both closer to the market than a naive model would be, but neither number is offered as a betting edge.
