Model accuracy + full history, in public

Our probabilities, measured in public.

We don't sell a betting edge — we sell accurate analysis. So we measure what actually matters for a decision-support tool: how well our fair-value probabilities match real outcomes (calibration), shown below in full. Our earlier +EV-pick experiment is kept underneath as a labeled archive — including the honest finding that the playable market is too thin to beat. Nothing hidden, nothing cherry-picked.

Across 392 settled predictions our fair value said 45.7% on average and 43.9% actually happened — the model's probabilities track real outcomes, and its Brier score beats the base-rate baseline beyond statistical noise — it adds real information. This measures accuracy, not profit: we're a decision-support tool, not a tipster.

Research-phase archive (retired) — our earlier +EV-pick experiment

Below is the full result history from when we tested publishing +EV betting picks. We've since found the playable market for our users (~2 GGL-licensed sportsbooks) is too thin to sustain a betting edge, so we repositioned to analytics. We keep every result here — wins, losses, and the finding itself — because deleting losers is what tipsters do. It is NOT how we measure the tool (see model accuracy above), and it is reported as independent decisions, not per-book rows.

Methodology

How we measure accuracy (calibration + CLV)

Our headline metric is calibration: across our settled predictions, does an outcome we put at probability p actually happen about p of the time? We publish the calibration curve (predicted vs actual) and a Brier score tested against the base-rate baseline, with a statistical-significance gate. It measures accuracy, not profit.

We also show Closing Line Value (CLV) honestly — how our published odds compared to the market's de-vigged close, including when it is negative. Formula: CLV% = (published_odds / closing_odds − 1) × 100

CLV is a transparency receipt from our retired +EV experiment, not a current edge claim: the playable market proved too thin to beat the closing line, so we dropped the profit framing and kept the numbers visible anyway.

Settlement rules

Each pick is settled against one of four outcomes: Won, Lost, Push, or Void.

Won: Selection correct. Profit = (odds − 1) × stake.
Lost: Selection incorrect. Profit = −stake (full loss).
Push: Bet cancelled by bookmaker (e.g. Asian handicap half). Stake refunded. Profit = 0 units.
Void: Match abandoned or selection suspended. Stake refunded. Profit = 0 units.

The pick_results table is database-enforced append-only — UPDATE and DELETE are blocked at the database level, so a settled result cannot be silently amended or removed after the fact.

All profit/loss figures use the tax-neutral formula. If a jurisdiction-specific adjustment applies it appears in the pick's audit page under “Edge (post-tax).”

Sample-size caveat

Statistical significance in sports betting requires a large sample. The conventional threshold for drawing firm conclusions is ~1,500 settled picks — at that depth, a consistently positive ROI is extremely unlikely to be variance alone.

BetEdge launched in May 2026 with a baseline of ~293 free picks. Every result is published regardless of sample depth — the receipts are the product. The n= · early-stage data chip on the dashboard is the honest signal: “real numbers, but interpret ROI with an appropriate confidence interval.”

Lock-in threshold: 1,500 picks. The chip disappears once that milestone is crossed. We do not cherry-pick which results to show.

FAQ

About the track record

How is ROI calculated?

ROI is cumulative profit divided by total stake, expressed as a percentage. Only settled picks are included. Example: if 100 units are staked and 8 units net profit results, ROI is 8%. We report both positive and negative ROI — the ledger is public regardless.

What is CLV?

Closing-Line Value (CLV) is the difference between the odds at which we placed the bet and the closing line at kickoff. Positive CLV means we secured a price the market later agreed was underpriced. It is the sharpest long-term indicator of whether an edge-finding method actually works.

Why does the chart show negative returns sometimes?

Because they happened. We publish every settled pick — winners and losers alike. Variance is real and hiding losing stretches would be dishonest. Full transparency means you see everything, including the drawdowns.

What counts as a settled pick?

A pick where the match has finished and the result was determined by the governing body. Pushes (draws on spread markets) and voids (cancelled matches, walkover results) are excluded from ROI calculations but remain visible in the ledger for completeness.

How do I know these numbers aren't cherry-picked?

Every settled pick is published here with its odds, result, CLV, and profit — winners and losers alike. Results are stored append-only: once a match settles, the row cannot be edited or deleted. We never remove losing picks or hide drawdowns. The complete ledger is on this page exactly as recorded.
