What Happened Yesterday

Wednesday was clean across the live book. Run Lines³ went 2-0, returned 1.23 units on a two-signal card. Baltimore took the Mets as +1.5 underdogs for 0.61 units. San Francisco covered the same line against St. Louis for 0.62 units. Both dogs delivered. The closing line value¹ suggests we entered late or the market moved against us after publish. Over the last seven days, that same model shows median CLV of flat zero, mean +6.56%. The overnight bleed was an anomaly. All-time, Run Lines hold median CLV of +0.48%, mean +5.06% across 105 graded signals. The process remains intact even when entry timing stumbles.

Shadow research exists to test frameworks before they touch real money. Yesterday it went 23-11 across two lanes. Hits Props OVER⁴ landed 6-3, lost 0.46 units, carried median CLV of -25.77% on a two-signal sample. Hits Props UNDER ran 17-8, grabbed 0.58 units back, median CLV flat at zero but mean CLV at -15.81% — a few outliers dragged the average down. The seven-day window shows the same pattern: UNDER median sits at -2.63%, OVER median at -26.39%. That gap — UNDER entering closer to closing price than OVER — suggests a structural difference in how the two sides of the market move. Shadow models are excluded from the official book, but they inform how we think about prop timing and where edge might live.

Cumulative picture as of Wednesday close: 113-66 live, +34.54 units, 19.30% ROI across 179 signals. Shadow sits at 718-383-5, -13.13 units, -1.19% ROI across 1,106 research grades. Total portfolio activity (not the official book): 831-449-5, +21.41 units, 1.67% ROI across 1,284 signals. Seven days ago, that same total ledger stood at 1,074 signals, +37.99 units, 3.54% ROI. We've added 210 signals and dropped 16.58 units in a week — variance doing what variance does. The live book absorbed none of that drawdown. Current streak: two winning days.

How the Projection Engine Did

Yesterday the engine published 1,365 player projections across 15 games covering 273 players. The research scoreboard is absent from this data drop, so we fall back to the directional read: largest average delta² sat in total bases at -0.40 and hits at -0.25. That means the engine projected hitters for more production than they delivered. If we project a player for 1.2 hits and he finishes with 1, that projection missed by 0.2. Aggregate that across 273 players and you see where -0.25 comes from. Mean absolute error⁸ and within-one percentages were not supplied, so we cannot quantify precision yesterday. What we do know: the engine tends to set an optimistic baseline when the slate runs large, and Wednesday's 15-game card fit that pattern.

In practice: if you're building parlays or DFS lineups around our projections, budget for the engine running a quarter-hit high per player. That's a known calibration tendency on heavy slates. Adjust your own thresholds accordingly, or wait for smaller cards where the engine tightens up.

Today's Card

Thursday brings nine games and 810 projections. Run Lines generated three signals. Hits Props OVER produced zero — the gate held, no card cleared the price bar. The strategy working. The board names one candidate today: Detroit Tigers +1.5 at Chicago White Sox, best price FanDuel at +168. Two additional Kelly-positive run-line candidates live on the Signal Board — we don't name them here to preserve free-tier parity. The rest, including all shadow research, lives behind the gate.

What This Means

Closing line value is a process metric, not a report card. Wednesday's live CLV ran negative overnight, but the seven-day and all-time windows show the model entering ahead of the market more often than not. Small samples swing. The ledger doesn't lie.

Definitions

• ¹ CLV (Closing Line Value) — whether the price we got beat the closing price. A measure of process quality, not profit or loss.
• ² Delta — the gap between our projection and the market's line for a player prop; the side where we'd have value.
• ³ Run Line — baseball's spread bet, typically ±1.5 runs.
• ⁴ Hits Props OVER/UNDER — a bet on whether a player records more or fewer hits than the posted line.
• ⁵ F5 Innings — first-five-innings result, isolating the starting pitchers.
• ⁶ ROI / units (u) — return per unit staked; +1.00u = one unit of profit.
• ⁷ LIVE / SHADOW / total portfolio — LIVE is the official real-money book; SHADOW is research tracked publicly but excluded from the official record; total = live + shadow combined.
• ⁸ Mean absolute error (MAE) — the average size of our miss, ignoring direction; lower is better.
