No side clears the 5-point value threshold at the opening line.
The gap uses whichever model you've selected. Value always comes from Market Margin, the one model whose
disagreements with the betting line were backtested (flagged sides returned about +8% for favorites and +18% for
underdogs on flat bets at the opening price across ~2,800 past fights). Other models' disagreements with the market
haven't held up, so they don't get a value flag. It's measured against the opening line — if the price has
moved, the edge will be different.

When it ends
"Over 1.5" means the fight lasts past the middle of round 2, the way sportsbooks settle it. Fair odds
are the break-even price with no vig, so compare them with a book's line.
On unseen fights this model beat the plain base rate by about 4%
(log loss; 51% of 3-round fights go the distance),
so treat it as a tilt away from the base rate, not a certainty.
