Documentation

You ask in plain language. It answers with its reasoning.

  1. You Where's the edge on tonight's slate? ↳ prop_slate(min_edge: 0.10) good-sport A handful of legs clear the bar. On batter props with a 10%+ edge, the model has hit -2% where the market priced 51% — pitcher strikeouts run overconfident, so they're scored on their own (next question). Two books are tight against the strongest one, so treat it as a lean, not a lock.
  2. You Is the model overconfident on pitcher strikeouts? ↳ model_performance(prop: "pitcher_strikeouts") good-sport Yes, about 14 points overconfident across 1863 graded bets, and it's the one prop type running a loss. I'd down-weight it until the re-audit lands.
  3. You Where's the smart money moving? ↳ smart_money(sport: "all") good-sport One side has steamed four points of implied probability since open across five books. That's a market signal, not my edge. I'm flagging it, not endorsing it.

Built to keep itself honest.

-2% hit 51% market

Calibration

It grades itself against what happened. On its batter-prop leans clearing a 10%+ edge, it has hit -2% where the market priced 51%. Pitcher strikeouts run the other way and are scored separately. On thin edges it's noise, and it tells you which is which.

MLB 78% NHL 46%

Closing-line value

Did it beat the closing line? That's the textbook sign an edge is real. On MLB, 78% of the time. On NHL, 46%: at market, and it says so.

Tennis +2.0% MLB −15%

It reports the misses

Over the last 30 days, tennis is up 2.0% across 72 graded bets, while MLB game lines came in about break-even. A good analyst shows the flat stretches and the misses, not just the wins.
