Martin DammvsAbdullah Shelbayh
4cx is paying 5.1% over the sharp consensus in the moneyline market, 10 hours before first serve
What happened: Final score: 2–0. This one lost. A real edge is a long-run average, not a per-bet promise — we publish every outcome either way. The closing line moved against the signal (-3.5% CLV) — honest note: on this one, the market did not confirm the edge. For the record: the flagged price stayed live for about 10 hours after detection before the edge closed.
