What the posted line does not say
A book shows one number. The product is the pair. Here is how to read it on any line, including ours.
Updated September 4, 2026
A posted price is one side of a pair. Add the two implied chances and they run past 100 percent. That extra is the hold if the money balances, and it is charged to both sides. Ledger prints that pair on every public game from the same multipliers the card already shows. Nothing on that plate is a lean.
What does a posted line leave out?
Take both prices, invert them, and add. A standard -110 / -110 pair implies 52.4 percent on each side, 104.8 percent posted. Reality only has 100 percent to hand out. The extra 4.8 points is the overround. If the money balances, the book keeps about 4.5 percent of everything wagered. A book prints one number. The product is the pair.
That arithmetic is the same one on how sportsbooks make money. The difference here is where it sits. Every game on Tonight’s board prints the posted pair and the hold from the multipliers on that card. The number is this line, not a typical month.
Can both sides be minus?
Yes. When both sides sit above 50 percent implied, both are priced as favorites. That is the vig, not two teams who both win. The dog can be juiced too. The side that sits further above its fair share is carrying more of the tax.
The fair read you see on Ledger is the pair with that tax divided out so the two sides add to 100. The posted pair is what a window actually hung. Both are true. Only one of them is usually printed.
What is a hook?
On football, 3 and 7 are the scores that decide the most games, then 6, 4, 10 and 14. A half-point on one of those numbers is a hook: land on 3 against -3.5 and the favorite still covers. A whole key number can push. Books do not label either. Ledger does, when the spread is a football line we actually posted.
We only name a hook on NFL, college football, and CFL, and only when the spread is a posted line we already carried. A baseball run line or a tennis game total does not borrow football’s key numbers.
Why do parlays pay less than the legs imply?
Every leg carries its own hold, and the legs multiply. Three fair coin-flip legs come in together one time in eight, so a fair slip pays 8.00x. Pay 7.00x instead and the stacked hold is 12.5 percent, nearly triple a straight -110 pair. Ledger prints that gap on a parlay slip from the legs' own fair reads against the posted price.
Promos cluster on that shelf because that is where the widest margin sits. A boosted parlay is still a pair of pairs, multiplied. The slip on Ledger names the stacked hold when the legs have a fair read.
What about live prices and cash-out?
A live number is the last posted pair, not the play that just happened. The book sees the play first. Cash-out is a new number, not the one you locked: Ledger's offer is the expected value of the ticket right now, and Standing does not move either way. A prediction market hides the same tax in the bid and the ask. We do not invent a closing-line grade we do not have.
A book can also cut a winner’s limit and leave a loser’s limit alone. Ledger cannot do that, because nothing here is cashed out of the building. The record is the product. The Shadow Line is what a real book would have kept from the calls you already lost, in dollars, understated on purpose.
