WNBA · MODEL PERFORMANCE

The whole record, one page

Spreads and totals, with the model’s number beside the market’s and the result that settled it, the same comparison the other six sports get. WNBA is paper tracked until enough data has been collected to determine a credible edge.

24 decided games cannot be read as a rate. The interval above spans 37 points, which is the honest width of what this sample can tell you.

What this model does not know

How to interpret this experiment

What this model does not know: it prices from team ratings and the posted line. It does not read injury reports, rest, travel or rotation news, and a late scratch it never saw is a game it priced wrong for a reason that has nothing to do with the model being right or wrong about the teams.

Calibration by edge

Spreads · 24 decided
Pick rules and edge bands

The fired picks split by how far the model was from the market. Every band starts at the 4-point threshold or above, because nothing below it fired. Bands with no picks are not shown rather than printed as zeroes.

How to read the edge intervals

Win rates in these bands are not colored against a break-even. At this sample size a band of two picks is a fact about two games, and coloring it green or red would dress it as a verdict. There is no ROI column because there is no wager: AVG CLV is what this sport publishes instead.

Why no trend curve is shown

The experiment has run 3 months. No curve is drawn: a line between two points is a slope, not a trend, and drawing it would suggest the record is moving in a direction.

The log

How to read this pick log

Every spread pick the model published, with the market’s closing number beside ours and which one landed closer. BBMI ERR and VEGAS ERR are each side’s projection against the actual, so CLOSER is decided by those two columns and nothing else. CLV is the separate question of which way the line moved after we published.
